Do you even know what you are talking about?
The USSR was a state controlled by the workers, while the Russian Federation is a state controlled by the russian capitalists.
Putin distorts the history of the USSR every time he speaks about it. He wants russians to think that Russia was "a glorious empire that almost beat the West", not a country led by the working class that gave hope to billions of people worldwide.
You do not know what fascism is. You do not know what communism is. Go read a book before you argue online, it is good for you.
I know that you did not read anything because of your mention of Tiananmen Square. You did not do any investigation on the subject nor did you read someone else's investigation into the subject. You just took the propaganda as truth and ran with it.
If you want to actually learn about communism, fascism, the USSR, China, Tiananmen Square, etc. you can just use the search function of lemmygrad. You'll find many resources to learn.
(or you can just continue helping the fascists by regurgitating propaganda, do whatever you want, I won't force you)
