Well, that was a pretty dark read. Sure is sad to see things like this coming around. Bible says there is neither Jew nor Greek, free nor slave. That's where I'm at. That's a damned shame the way things worked out.
What I read of it seemed like a fed-entrapment edit. "Hi, I'm from 4chan. 4chan made me racist. I love guns and white nationalism. I also love these other websites."
I don't doubt that 18-year olds are dumb enough to believe it all earnestly, but arriving at it organically in this climate is farfetched. /pol/ hasn't had that kind of ideological oompf or coherence for half a decade.
