It's not denial, it's placing rightful blame. It was a Nazi massacre.

Soviets never liked the Jews but had Jewish founders and leadership and laws protecting them that were the most supportive in Europe? Incredible. Where was a better place for Jews in Europe? Germany? France?

The Soviets never admitted it. The post-Soviet government is still unsealing documents with no proof of it being committed by the USSR.

You've literally lied about multiple things in this post to push a narrative that supports your own political bias. Or are we already forgetting about the Jewish doctor from my previous comment with more awards from the Soviet government than most non-Jewish doctors?
