>Jews have proven themselves to be some of the worst creatures to ever exist
Do you mean Jews as in the psuedo-race or as in the religion? I'm not a fan of the Jewish religion but I'm not a fan of any religion. Synagogues weren't allowed in the USSR. 
>but something tells me you will try to justify killing Millions of peasants because they had an extra cow or something
They were killed because they would rather slaughter the cow than give it up to the common good. They were enemies of the working class.
