My husband was a Berkeley student in the ‘70s and pretty apolitical when he went in. Being around, and observing, the idiot liberals there, he became a staunch Conservative.
UT Austin in the late 80s had about the same effect on me. I was in the business school so most of my peers were relatively conservative, but it seemed like every other day there would be some kind of lesbo, gaybo, bed-in, protest, blah blah in the Free Speech area outside the Union. That was when it first occurred to me that political correctness was coming to America.
