I don't mean to pick a location as THE place ignorance comes from. At least not the place that ignorance MUST come from. There are plenty of good, decent, thoughtful Texans. In fact, one of my oldest Democratic friends lives there. But Texas, for whatever reason, owns a lot of this particular brand of ignorance. Think of the school board's decision to take Jefferson out of the curriculum to replace him with a religious figure (

Like I said, Texas may not be the only place to find stupidity, but if my life was on the line and somebody was asking me to throw a dart at the map and hit a conservative with more fervor than sense, I'd aim for Texas.
But, to your point, maybe I should have added a few more - Florida, Georgia, Virginia, North Carolina, West Virginia and Indiana...all places I've lived in long enough to find plenty of the type of Republican mindlessness I was referring to.
