One of the foundations of capitalism is the strict enforcement of gender binary, and the move from matriarchy to patriarchy (from men needing to enforce monogamy for women, to know who their children are, to ensure passing down and consolidating of wealth)

so yeah trans people, gender non conforming folks, and people practicing non monogamy are a threat to the system, but not in the way theyre proposing

read the origin of the family by F Engles, there’s also a section in transgender warriors by L Leinberg
