One thing I've seen over and over on
This fits in with a theory that I have held for some time, that Leftism is a religion. Leftists can't stand having thier "theology" challenged, they often react to these "heritical" challenges with attempts to silence those who are opposed to the "faith".
Note how often Leftists attempt to portray those who aren't "beleavers" in their "Religion" as evil, something that is typical of religous fundementalists.
Leftism has it's assorted "prophets" who's "revalations" are accepted on faith, the reactions to challenges to these "devine revalations" mirror those you get from the far right Xtians when the Bible is challenged.
All in all Leftism has to be considered a religion, and one that is every bit as intolarant as Fundy Xtanity or Wahibist Islam.
