Fanatics are like that.
I've got some in my office (one especially in my department) that's a moveon.org sort of uber-liberal.
We don't talk politics anymore. Some months ago I wuz buyin' him a beer at da waterin' hole and he went totally non-linear on Bush, and in a surprisingly mouth-lathering shaking and shuddering sort of way.
He really, honestly, believes that Bush intends to suspend the constitution and set up some kind of religious taliban government (except Christian) with Ashcroft as a new ruler-Pope and end all elections. Anybody found to be non-christian will of course be jailed and beaten and tortured into submission. All of this of course is to further the hatred begun by right-wing bigots against muslims.
This is no joke. They really believe this stuff.
