Though Trotsky was of Jewish heritage, certainly he did not adhere to that religion.
DNA analysis revealed that Hitler had Jewish and Berber markers in his DNA. Still, that doesn’t make him a Jew, and nor does his great guilt apply to the Jews of today.
I am not applying guilt, but I cannot be proud that Bolshevics were predominantly Jews. Sorry I feel that way. And please don’t mix Jews as an ethnic group with Judaists as people professing Judaism. Not all Jews are Judaists and not all Judaists are Jews. Bolshevics were atheists but they were (not all of them) Jews.
