You seem to be confused.
The doctors plot happened. Many Jewish people were rounded up tortured and executed by the regime! People died for being Jewish. Stalin died before rounding up all the Jews but the communist party rounded up and killed Jews for being Jews. That happened.
“And this wasn’t an isolated incident. It came after several years of increasingly antisemitic repression under Stalin, including the campaign against supposed “cosmopolitans” and the destruction of the Jewish Anti-Fascist Committee”
Oh I see all the racism in Russia is actually everyone else’s fault not Russia. Got it.
The Han Chinese were already racist before communism so it doesn’t count either.
Wow I’m so glad communists regimes can’t be racist because nothing counts.
You say I have “one” example. The truth is I just don’t have all day to list the many many examples. Especially since after each example I give you’ll only stomp your feet and say “that doesn’t count!” Every time. What’s the point.
