Alot of the "altrighters" came from a bunch of young guys who voted for Obama for change and hated Bush and McCain. Were fine with gays being gay as it didn't spill into their lives. Hated that Wall St. got bailed out.
Then things got weird and media started overtly saying how all whites were evil and racist, it's better to be gay and let your kids join in, and the flip began.
This is concise and astute. Many people "radicalized" simply by staying the way they were and being vocal about lines they don't want to cross. The crime of being loud enough to interfere with the divide and conquer strategy used against themselves, their friends, and their neighbours.
It's a damned if you do damned if you don't. If you don't, you get swept up, if you do you get to play the heel for a mob that won't look up.
