There was so much going on when Toffler's book came out. Future Shock -- was being shown via flick in schools (e.g., "shock issues" -- the earth was ending, recycling would save the planet, we were all going to be nuked off the planet, men evil/women good) - I can understand your conservative professors' concern. But OTOH, their demand of you; made you think good and hard, no?
They were good. I think that they learned that even the liberal Toffler had some things of value. Not all liberals do!
