I don't know much about the subject specifically in Gaza or in Palestine in general, aside from this academic paper which is about the use of pinkwashing as a colonizer tactic. Regarding advocacy groups it mentions the group alQaws. Here is an article by alQaws: Queer Liberation & Palestine. Quote from article in which they warn about the weaponization of LGBTQ issues to further colonial agendas:

Israeli settler colonialism, and tactics such as “pinkwashing” weaponize our queer experiences to place us in opposition to our own society and communities. Pinkwashing is a form of colonial violence. It promotes harmful narratives and policies that alienate queer Palestinians from our own communities. Our answer to pinkwashing is to say that liberation is indivisible, and that there will be a place for all of us at the rendezvous of victory. The Israeli criminal government and Zionist LGBTQ movement manipulate and exploit queer Palestinians’ lived realities to advance a colonial agenda. The standards for solidarity and action cannot be set by the colonizer.

Another article from them: No Queer “Co-Resistance” with Colonizers: Confronting Normalization and Pinkwashing

In alliance with anti-colonial coalitions, alQaws developed and popularized the concept of “pinkwashing” to expose how Israel and its defenders use the language of LGBTQ rights to distract from the oppression of Palestinians. Over the years, Palestinian activists came to recognize that pinkwashing is not simply an outward-facing propaganda machine—it is a direct form of colonial violence, one that pushes Palestinians to view ourselves and our communities through the lens of colonial prejudice.

Pinkwashing relies on exploiting progressive rhetoric about “tolerance” and “gay rights,” to conceal the violent nature of the occupation and settler-colonialism in Palestine. Normalization, similarly, draws on liberal ideals of “dialogue” and “partnership.”

5 Way to Support Palestinian Queers

Perpetuating tiresome tropes of presenting Palestinians as inherently oppressive and Israel as a liberal state that protects LGBTQ rights is counter-productive and factually baseless. Israel is a settler-colonial state that offers no rights to Palestinians, queer or otherwise. Our struggle as queer Palestinians is against Israeli colonialism as much as it is against homophobia and patriarchy in Palestine. Israel uses pinkwashing tactics to lie about “saving” LGBTQ Palestinians from their society. We ask that you steer away from these lies that are intentionally used to justify their colonization of Palestine. alQaws and our allies in Palestine will continue to amplify our message as well as provide protection and a political home for LGBTQ Palestinians. Israeli LGBTQ groups do not have a say in the work that should be done to fight patriarchy and homophobia in Palestine, including the incitements led by the Palestinian police.

As I said, I don't know much about it beyond the above, which I have not looked deeply into, so take this information with a grain of salt.

I suggest studying some Korean history and reading the works of DPRK's leaders and other DPRK authors directly and over time you can form your own evaluation of what they believe and why they have implemented particular policies at various times. I don't have time to write more on it at the moment but you can find some of Kim Jong Il's views on Marxism, Marxism-Leninism, socialist construction, and Juche here.

The "patsoc" ideas which promote patriotism in the imperial core and reject decolonization are much different from the socialist patriotism which is anti-imperialist and decolonial. DPRK does uphold socialist patriotism, which is regarded as part of its internationalist duty of completing the Korean revolution by focusing the majority of its attention on Korea, to make sure their revolution is successfully carried out, and which is specifically against promoting national chauvinism, and rejects racism.

DPRK's emphasis on looking inward for solving its problems and on self-reliance come from Korea's specific conditions. Specifically, Korea has been a battleground for world powers for much of its existence and historically had strong ideological currents of subservience to larger powers influencing its politics, which posed obstacles for progressive/revolutionary movements in Korea since feudal times and into the modern era. After DPRK was formed, it also had to deal with the issue of different influential strains of thought among socialist countries, including its powerful neighbors, Russia and China, during the Sino-Soviet split. The opening of China and the fall of the Soviet Union led to further inner debates. DPRK's emphasis on focusing on its own conditions is a necessity for it to avoid dogmatically following other states' lines and thus committing errors in its own revolution, not a blanket rejection of foreign ideas.

I am still learning about Songun, but from what I have read so far, it seems to have its roots in the Cuban missile crisis where US aggressions were ramping up, and finally came to the fore as policy during the Arduous March, when the US was trying to use the economic upheavals after the fall of the Soviet Union, with the US attempting to end DPRK by intentionally starving its people to death. It was determined that in order for Korea to complete its revolution and defend socialism, it would be necessary to heavily prioritize defense due to DPRK being under constant mortal threat from imperialism. Edit: Also, with DPRK's more recent nuclear developments, I believe the policy of Byungjin (parallel development of military and economy) has returned to the fore, though I may be wrong about that. I'd appreciate being corrected if someone knows.

I recommend this essay on ProleWiki, The Cleanest Farce: How "Experts" Distort the DPRK, and the page about Juche which has sections about Juche's relationship to dialectical materialism and to Marxism-Leninism specifically. Tl;dr is that ML is seen as a correct revolutionary idea but that it, being very old by now and being formulated in the world's first successful socialist revolution, it lacks certain concrete details about socialist construction in the present day and also (naturally) has a different context than Korea's revolution. Therefore it is regarded as a basically correct idea for revolutionaries to follow, but that following it dogmatically is an insufficient application of it, and all countries will need to forge their own path to suit their own conditions as they are confronted with the task of socialist construction and defending the revolution in the present conditions. Juche takes the dialectical materialist view of the world, and it is just dealing more with how people can have a certain attitude and point of view to successfully carry out revolution.

1. It seems fine to me as a concept, as it doesn't strike me as much different than any book which has multiple introductions as different publishers pick it up over time. There could also be a page somewhere, "About ProleWiki introductions" which is linked at the start of each of these intros. The page could explain the overall method behind how and why these intros are written and when the implementation of this feature began, for transparency.
2. Possibly.
3. Unsure on this. I think more detailed opinions and interpretations might be better placed in an essay, perhaps books in the library can have a section at the beginning after the contextual introduction, or on a related page, in which editors may add links to opinion/interpretation essays on the work, perhaps limited to essays which were specifically written and submitted as introductions for the work (rather than just any essay about the work), or with section headings separating introduction essays from other types of essays on the work. However, as I said, I am unsure.
4. Somewhat concerned, but as it hasn't been implemented yet, I want to see what happens in practice with a few works.
5. Nothing comes to mind right away but I will keep this question in mind next time I access a work on the library.
6. "Introduction to the ProleWiki edition", possible link to "about ProleWiki intros" page suggested above, the intro itself, ending with the date it was written and names of its author(s). Footnotes could start with "(PW)" or something similar.
7. (1) In general I am happy to see things like this being tried out, whatever the results may be. (2) This makes me curious as to whether things like comprehension questions (such as for self study or study groups) could also be appended to some works in a similar way, if there is interest in it and if the introductions concept seems to be working smoothly? As well as other forms of extra material that might appear in the end of a book, I am curious whether there is interest in that type of thing or other extra material (beyond what can already be accomplished as essays which are not specifically linked or included in a work).

I don't unfortunately

United Nations Population Fund's summary of DPRK's 2008 census: "Housing is provided by the government free of charge. It is the responsibility of the state to provide housing to everyone. Hence, there is no homeless population." (p. 4)

Unfortunately, I haven't yet double-checked that particular document's authorship (i.e., is it the UNFPA summary as the uploader's description states? Or is it the summary that DPRK's statistics bureau submitted to UNFPA? Or something else?), so take it with a grain of salt and try to verify it if you're going to be using that quote for something.
