Why should Nazis and Communists fight?

Why should Nazis and Communists fight? After all, both groups have single enemy - the Jews (Zionists). Communists, being politically correct, just call jews "bourgeoisie" (capitalists). Both, Nazis and Communists, depend of altruism, when every agent should act for common good. Both, Nazis and Communists, oppose modern religions, because religions lost their original purpose to serve as a guiding light and now support unjust exploitation of people by the jews. Both, Nazis and Communists, fight against evil government (ZOG) and support "think global, act local" principle of Anarchism. Both, Nazis and Communists, practice self-organization: KKK members lynched jews, defending the interest of their community, just like Communists defend their communal rights.

I see no barrier for consolidation.

But Jews were behind communism and the murder of 25 million white Russians in labour camps.
