So why all the French hate?

EXPLAIN!!!

Or is it just because the french were such an ass for not going to war with US?

it removes the ability to make decisions based upon logic.

As opposed to taking everything at face value? If the premises are false, then what? Sound arguments fall apart. In other words, you can't have any confidence in the conclusion either... just like a skeptic.

Science also is based on skepticism. "It does that because of X." "Oh, really? Please support that, and then I'll go replicate it."

Skepticism isn't either/or. It's a continuous spectrum, just like most things in life. I don't know anybody who abides by its most extreme forms.
