Brow beating someone into one view of political correctness is just the liberal form of "Mrs. Grundy-ism" and defacto censorship. Using peer pressure or shouting someone down (not in that thread but a common form of protest) are only different tactics to achieve the same -- result stopping certain people you don't agree with from saying what they want to.

It looks like you're suggesting that only people you call "liberals" use these tactics, Strick.
