Let's not forget -- the population of SC is only about 4.8 million people. Of the states you listed, only Arkansas and Mississippi are smaller. Moreover, having a large number of hate groups per capita -- which SC does -- doesn't mean that the groups have many practicing members.
Not to belabor the argument of SC having lots of racists, but raw numbers don't tell a very informed story. And frankly, this man could have become racist with or without groups.
Thank you , I had not considered the states' population. I agree with you , he could of become a racist with or without groups .
