As i always say its not the communists its the tankies. Communists want a different economic system but still agree on the equality of people and they can either want an autocratic or democratic system(from what i see simple communists usually want democracy). Then theres the tankies. They support full autocratic governments that are usually not even communitst like china and want a violent revolution.

What do you mean by an "autocratic system?" All Communists support democratic systems, the idea of there being some especially evil Communists that don't want democratic systems is unfounded. Additionally, all Communists want revolution, reformism is anti-Marxist to the core. The State and Revolution is around 25% Marx and Engels quotes and goes over why Marxists believe Revolution is the only path to Communism, and goes over how to make a far more democratic government.

Often times they are even transphobic.

Who? The far-right American Communist Party are not Communists and reject Marxism. The 3 most Communist-friendly Lemmy instances are the most militantly defensive of trans individuals on Lemmy.
