As this Economist article makes clear (but perhaps not clear enough), despite its propaganda, Israel is not interested in Palestinian gay men except as vulnerable subjects to blackmail and make into collaborators.
The article is exclusively about gay Palestinian men, not women, who do not have the men's particular experience. However, Israel's Shin Beit has used attitudes to women's sexuality as a way to blackmail both non-gay men and women into collaboration.
The only way to prevent such blackmail is to fight against homophobia and sexual discrimination in Palestinian society. Among other things, they do leave Palestinian society vulnerable for exploitation of this kind. But if men and women, gay and straight, are not made to feel ashamed of their sexuality, if their sexual choices are not criminalized, then they will not be such easy victims of colonial blackmail.
In other words, speaking up against homophobia and sexual discrimination should be part of an anti-colonial national resistance strategy.
