And, in conclusion:
We could keep this up all day, I suspect. Remember, the point isn't that the American Taliban is just like Al Qaida (though given the chance...), the point is that there's no reason that liberals would ever "root" for Al Qaida or the Taliban or any of the crazies in the Islamic fundamentalist world.
The reasons we hate the American Taliban are the same reasons we hate fundamentalists of all stripes -- they seek to impose their own moral code on the rest of society, and do so with the zeal and moral absolutism possible only from those who believe they are doing "God's work".
