I’ve long heard from people who have lived around the U.S. that blacks are treated much better in the South than in the North and other “non-South” states. Hmmmmm...
Racism has always been practiced more intensely in liberal states. Maintaining rigid welfare ghettos, restricting economic opportunity to minorities, and installing race baiting politicians are common practices in liberal northern states.
Might I suggest that historically, Southerners more often saw blacks as helpful servants, whereas Northerners saw them as unwelcomed competitors for low-wage jobs?
Today things are somewhat different, and I'm not certain if anyone can really say: how much does, oh, say, inner-city Atlanta differ from, say, inner-city Philadelphia?
