I am glad I was in gradeschool and not in college at that time. But even so, as a child, I thought they were irreverant and destructive.
I was in grade school in the sixties. The protesters just looked like spoiled whiners with nothing better to do. Happily by the time I got to college, protesting wasn't a popular past-time, although some of my instructors looked like leftovers from that era.
