I'm not saying all this to imply that /pol/ is even handed but they simply don't talk like "white people have bad food! Lol they season turkey with water!". The entire self justification for their behavior in many cases revolves around believing others hate them as much as they hate others, and people are liable to spread anti-white hate speech just to agitate.
That other stuff? That got you mad. You've got multiple threads running about how terrible it is - and there's a good chance you don't even identify as one of those groups.
But let's assume for a moment that 4chan really is concentrated evil. You do realize you are basically advertising for them right now?
Does one have to be non-White to be opposed to the mass murder of non-Whites? Shouldn't every non-racist psychopath White person be offended by the idea of mass murdering non-Whites?
They tell jokes about white ethnicities, but don't speak unironically, constantly, and at length about why whites should be racially exterminated like they do towards non-Whites, Jews, Muslims.
