I organize with trans communists all the time and materially support trans spaces. There is no lack of trans people that oppose both capitalist parties. But more importantly, if you are to avoid tokenizing people, you must have an actual analysis for liberation and not a monolithic "this is what trans people want" stereotyping. The latter is always incorrect and never actually happens because trans people are not a monolith. The former just means you understand this and know which trans people you disagree with. For example, I disagree with assimilationists that support genocidal Democrats and try to pretend liberation comes at the expense of others.
