I'd also like to point out that these sorts of things flourish just because of ignorance. There are many communists in places like China, Czechia, Vietnam, Cuba, and so on, that if you properly educate them on LGBT issues, they become stalwart allies in quick fashion. They legitimately have never been exposed to the idea of LGBT people beyond the surface level. My grandma, for instance, was a commie organizer a long time ago and since I have come out to her she did a complete 180 on LGBT issues and has even pushed all of her connections to be accepting as well. It required almost no pushing from me for her to do so, she educated herself and asked for book recommendations even.
But you also have to realize too that there are many reactionary groups that take advantage of this ignorance to stifle the LGBT community. And there are international liberal groups that seek to turn LGBT people into compradors and spies because of their precarious condition. It is very convenient for these liberal groups, LGBT people are everywhere and since we generally have it bad in every country, they can point to the miniscule amount of progress in the West to show these people 'hope' through intervention. It is very sinister, and it is an issue that comes up a lot in my discussions with LGBT people abroad. Some LGBT groups in countries like China even have rules about not speaking to foreigners for this fear that it could cause trouble. So this sort of rhetoric just ends up making the situation even more precarious and it makes it harder for people to find legitimate, altruistic help.
