Okay how about this. Tell me which policies of the USSR were racist, who they were racist against and why you think they were racist.
> institutionally targeted programs were to enforce political control and break nationalistic tendencies of ethnic groups.
If that's not "institutional racism", I don't know what is.
This literally means stop nationalist secession movements. Literally no country on earth basically lets their citizens secede dude. Russians were ALSO the target of such programs.
It's like saying state atheism is uniquely Islamophobic or uniquely anti christian or uniquely antisemitic.
I'm not saying it's not repression. It totally is, but it's not racist.
