I spent more than half my life living in the South, Bears.
Maybe in some sick, twisted way, you want it to be 10% haters, but that still doesn't make it so.
Even the SPLC shows that the number of hate groups seems to follow the population, not antebellum geography.

You like to pick on Texas, yet CA, NY, NJ, and PA each have more hate groups than TX does.
930 of these groups, and I'll guess they probably average 20 members each at most. You're talking about at most 20,000 people who SPLC identifies (and they include the Westboro's of the world plus ultra-fundamentalist Christian groups who are anti-gay marriage in that 930 number, even though those groups don't target people on race) as hate groups.
That's 99.993939394 % based on a population of 330M people in the US.
To reach your idiotic 90% number, for every 1 person who is actually a skinhead racist, you'd need 10 people to agree with them.
I find that morally and statistically impossible to achieve.
But, you can keep fomenting the concept that there are between 10 and 20 million skinhead & KKK sympathisers in the U.S. It just makes you look as ignorant and narrow-minded as the people committing those crimes.
