The claim I gave was that the Soviet Union was historically progressive compared to peer capitalist countries. I never said they were progressive compared to modern western countries when it comes to queer rights, and when it comes to women's rights, worker's rights, and more, the Soviet Union was more progressive than the US is today. You are shifting the goalpost to the idea that I said the Soviet Union was flawless even by modern standards, which I never said.
Further, you again try to draw a direct line from a socialist federation of countries to the horrendously reactionary states that replaced them. There is no material basis for this, otherwise the Tsarist system would have continued culturally into the Soviet system. They clearly did not, the Soviet Union was enormously progressive compared to the Tsarist system, just like the modern reactionary states are far more reactionary than the Soviet Union was.
You have no leg to stand on.
