Just like any other crime, it depends on the reasons. Do you have some reason to think the police ignore/downplay crimes committed against white people, or prosecutors are reluctant to bring the most serious charges against suspects when the victims are white? Let me reassure you, whitey; white victims get better police response, and their assailants get much stiffer penalties, than happens for black victims.
You mean, like when that black kids car broke down, and he knocked on a couple of doors trying to get help, but the white kids decided he was a threat, so they killed him? You don't think that's racism in play?
It would help if there were more of a relationship between your hypotheses and reality.
Racism is defined by the social oppression directed at people because of the color of their skin. I agree that skin color is not the relevant factor in the definition, but it is relevant in any individual application. You have never experienced racism, obviously.
Right there you lose me. How would you know? It is an assumption based on him being white. But you know nothing about what he has experienced, where he has lived, his families wealth, or lack there of, or any other relevant factors needed to even begin to discuss wether to make that claim.
I'd tend towards we have all experienced racism in some form or another to one degree or another.
