I wonder what the overlap between this and troons being into Marxism is.
Other than what you stated, I don't think there's as much as you think.
@Safir said it best when he said that the real reason why many western troons and wokists go for communism is because they're contrarians who feel no kinship with the society they live in, and will go for any ideology that their community sees as the enemy. Essentially, sexual degeneracy is also co-morbid with a pathological desire to commit treason for shits and giggles. Irrational hatred for their community, anti-social behavior.
Many communists have stated that homosexuality and transgenderism are both forms of bourgeoisie decadence, and it's surprisingly easy to explain why, in a way that is perfectly consistent with the framework of communism or socialism. It matters not to these troons.
It's also the same reason why a surprisingly large number of troons also go for neo-nazism or alt-right ideologies, as those ideologies are also seen as antithetical to western values. However, they do prefer communism because it's easier to virtue signal about how much of a good person you are under the framework of communism than nazism.
Nazis are honest about the fact that their ideology involves mass-murder and dehumanization of various ethnicities seen as the "enemy." On the other hand, commies and anarchists can easily gaslight people by claiming that their ideology is just about "sharing is caring," or "equality," or "kindness."
Hence commie troons can continue to pretend to be the good guys, even as they cling to an ideology that is explicitly about the confiscation of property, the mass murder of anyone who objects, and even the mass murder of anyone perceived to be a "reactionary."
