<I see the manifestation of freedom of expression.

Just because they have the right to say something doesn't mean they aren't full of crap. Freedom of speech does not imply immunity from criticism, although many attempts are made to blur this distinction.

...And, above all, I see the recognition it's not just a battle between "good" and "evil": I agree with that.

You damn right it's a battle between good and evil, and the attempt to create a moral fog in which such categories are defined out of existence is one of the ways that evil gets the job done. This moral neutrality is one of the big things kids learn at universities. Oddly, when the Left opposes something, the idea of "evil" suddenly pops up for ready use again. When ideas the Left are opposed to are raised on campuses, books and newspapers are stolen and burned, and speakers are run off the campus. Conversely, when questions arise on the actions of the Left, it suddenly becomes "who are we to make judgments?"

And just out of curiosity, exactly what in your opinion would someone have to do to us before they could be considered "evil?"
