Do yourself a favour and look up the definition of the word "racism" in a dictionary from the 1930s or 40s, or from a 100 years ago, before embarrasing yourself in front of the whole world by spouting conventional wisdom/MSM nonsense. Somebody invents the concepts and words that go along with them that make people like you feel guilty and apologetic for the progress of humanity.
Jerry Seinfeld realized his friend screwed up and there is no excuse for what he did. Why can't you accept that, instead of defending and minimizing?
None of which has anything to do with your farcical notion that the KGB invented racism. Did the Soviets exploit a divide in American culture? Absolutely. That's what enemies do. But the divide was created by Jim Crow, not Joe Stalin.
