That manifesto at your link, if that is what it is, is pretty incredible. The guy is obviously very intelligent to have produced something so long and well written, but where on earth did he grab hold of such ideas about Jews? He goes beyond even the worst stereotypes that have been thrown around for centuries.
And he says his parents didn't teach him those things, but should have. He seems to have latched onto one or two false ideas, accepted them totally, and then built his entire outlook upon those.
The Internet, probably. Search too much about World War II and present-day Nazi sites come up.
That's what leapt out at me.
You would have thought he had a lifetime of horrible experiences with Jews.
That doesn't seem to be the case.
I think it is a mental disorder fueled by internet support for his opinions. - Tom
