Why do leftists blame all of the worlds problems on working class white men, even though we have zero systemic power ?

Hey, it’s your fantasy.

Because they are communists. They want to create class war, race war.

They learned their anti-white BS from black people. black people are the root of all this sjw/anti-white BS. 

You blame it on the elite and minorities even though we have no power

We don't.  Capitalists steal from labor.  That's why we should have worker cooperatives.
