As I said above, I'm pretty sure that if that cop identify you to the disfranchised white population, your luck will be barely better if it's better at all than if you're part of the disfranchised black population. I heard the term "wh*te tr*sh" used.
Think I fixed a typo in there. Though -- I've lived in areas that's about as much trailer trash (the more inclusive term, though honestly, white trash is barely a slur in this country, or at least the parts of it where trailer trash is common) as not pretty much my entire life. You would be
hilariously wrong. Yeah, a homeless white guy or panhandler is probably going to be harassed by the cops. But they're
not going to be harassed as hard, nor is the probability of harassment as high to begin with, as a homeless black fellow would.
And again, as has been noted. Domestic disputes in poor areas? Black family, shit is probably about to go down when the cops hit the scene. White family, chance of shit going down
considerably less likely. Same social situation. Same extent of disenfranchisement. Literal only difference is skin color. There's patterns like that throughout the entire freaking country.
US has issues with classism, sure. Lotta' hate for poor people. But the country absolutely has a racism issue, that is distinct and separate (albeit definitely interacting) from the classism one. The country has definite and systemic issues with treating people of color, particular black people, disproportionately poorly. Definite and systemic issues with treating poor people disproportionately poorly,
too, but no, it's not the classism being misconstrued as racism.
Can understand why you have problems wrapping your head around it -- you're from a very different cultural area. But. No, there's not another explanation for what's going on in the states. Country, and particularly the legal system, is in fact pretty damn racist. Not really as bad as it used to be, but it's still pretty bad.
