Agree.
I know I sound like a jerk in my reply to the OP, but this stuff is why Liberals continue to kick our teeth in. The OP posted a good academic argument that would be good for conservatives only to read, but it contains no useful or compelling information for anybody other than a Civil War buff.
It's also yet another example of the Conservative argument that has failed so miserably so many times for so many years........
"I'm not racist. Let me convince you with facts and logic about how I'm not racist. I'm not racist, listen carefully and I'll explain it to you."
Yes, sadly I have come to realize that the bottom has dropped out of the market for logic in this country.
