"Because I kid you not, I have heard people say weather is racist, straight-faced seriously! One guy told me it is due to gentrification. Black people were intentionally huddled into areas with bad weather conditions. (And obviously they can't just move, right?)"
That´s the point of "gentrification".
Stop ungentle people from "just moving" into gentrified areas. If they "just move" out of a ghetto, the only place they can move to is another ghetto.
