Your "asshole" situation, is a little different than situations of systemic oppression that some groups experiences because of the color of their skin for instance.
I may have labeled it "an encounter with an asshole", but it was your example.
I am treated fairly when I enter a store or interact with people in general. I'm not followed around unnecessarily and I never hear racial slurs or experience micro-aggression's.
I've been stopped a few times and had a gun pointed at me as the cop approached my car. But you know what's interesting? You've admitted you don't have any real experience in this sort of thing and are telling ME, who has, the ways of the world.
It's not just black people getting shot. Fairly recently white guy (wearing black) who got blown away (with an automatic rifle) for pulling his pants up. It's not race that's the problem. It's the police policy of "shooting first, asking questions later." Or, as they call it "officer safety."
THAT's the problem with police shootings. Don't take my word for it, see it for yourself:
The above video happened because the guy matched the description and his only crime was being at the wrong place at the wrong time. Also notice, it's not on a dark street.
