Dylan Roof was influenced by a broken family and drug use.
This current fetish with flags will not prevent the next Dylan Roof one bit.
I think the intention is to poke and provoke people, to get a reaction. I can't think of a way to count up the nutcases on the two sides, one side being inclined to act if the flag stays (status quo), the other side being inclined to act if the flag is "banned."
Politicians, the "you hired us to do something, and by golly we will" pod-people.
