The Institute of Sex Research was burned down in 1933. It wasn't a "different time", it was a time with the same political issues and the same Nazi rhetoric attacking trans people. Had something been done to prevent the rise of the Nazis and protect the Institute of Sex Research, trans healthcare would be 50 years ahead in technology and we wouldn't be facing the same issues today. But Genocide Joe (the Russian one) opted not to do anything about the Nazis until 8 years later when Hitler brought the war to Russia.
Genocide Joe was aware of the issues. He chose not to protect trans people, and he chose to persecute gay people. Marx said a worldwide revolution would be required, but Joe said fuck that, homosexuality is bourgeois, and stayed in Russia. He is in large part responsible for the current plight of LGBT people.
I ask you, what state would the world be in if we had had a progressive Soviet Union? One that was 50 years ahead of the states on queer issues? One that was committed to racial and religious equality? How would the fight for global communism be going today if Genocide Joe had not armed the US with material for their propaganda that claims communism is right wing? If everyone in the world knew today that the USSR had been a haven for queer and Jewish people, decades ahead of the capitalist regimes, how easy would it be to persuade people into allies of the communist cause today? How much would a genuinely positive example help us?
Joseph Stalin fought the Nazis on the battlefield, but he was their ally in the cause of bigotry and hate. He had every opportunity to choose to become a progressive, and he refused. Fuck him.
