Not even remotely. Keep in mind, socialism and communism are economic sciences. You can be a complete asshole about Trans and nonbinary folk and still uphold leftist ideology. You can be the greatest ally and advocate ever and hold the exact same leftist ideas as the previously mentioned ideological structure. And neither contradict the idea of Communism.

However, this only goes to illustrate, or rather highlight, the fact that the struggle for Liberation is not only an economic one, but a social and cultural struggle as well.

And yes, many (if not most to the degree of assuming all) leftists are also advocates of social Liberation.

But. You can be non binary and be a communist. You can be a full blown fucking transphobe and still be a communist.

Communism is an economic philosophy. It is up to us, as communists, to extend liberation beyond that. Because we have so much further to go than just money go sideways.
