>I can't possibly imagine being this angry
You should probably get your testosterone checked, maybe they could give you something and you'd stop being as much of a faggot.
>What did Jews or black people ever do to you? 
On a personal level? Jews have spread degeneracy and ruined modern culture, blacks have ruined my city and turned it into a crime infested shithole. Those are just two of the many reasons my life and the lives of my family and the lives of my friends would be better if both groups ceased to exist. 

The better question is why do you worship kikes and niggers? Both groups are a net negative to the world, even smart blacks realize the world would be better off without blacks. So what are you, a brainwashed useful idiot or subhuman trying to justify your existence?
