That's an excellent insight -- I've long felt that there are parallels between Islam's cultish Us versus Them mentality. The same kind of purity tests, the same ostracism for daring to dissent, the same dismissal of criticism, the same inability to self-reflect, the same guerrilla tactics and threats of violence masquerading as "self-defense," the same belief that the ends justify whatever means necessary to spread a toxic ideology.

It's worth remembering that Leftist terrorism through history is second only to Islamic terrorism in its global destruction. And we find ourselves once again in an era of Weather Underground and Baader-Meinhof. Because like Islamic radicals, Leftist radicals are determined to repeat a doomed history because they haven't read more than one book.
