I appreciate your post.
I was a child of the '60's. I came to FSU in '69. Radical Jack on campus. I never went to any protests because of my dad and brother.
Every time I was home on break, the base commander used to stop by the house and ask me about the classes I was taking and I told him. I showed him the books I was reading, especially from a class called "Philosophy of National Liberation Movements". We read Mao's little red book, writings of Ho Chi Minh, and Lenin and Trotsky. Trust me, I was grilled, but never once was anyone upset with what I was learning. I was not taught to be a terrorist. I was taught what terrorism looks like and what the philosophy behind the cells were. The AF brass were not upset at all re what I was learning, it was history, and it's out there. They were impressed that I learned what motivates terrorism, and how cells operate.
Yes, FSU was the Berkley of the South then, but never once was I taught to be anti US.
Divisiveness and polarization has never been as bad as it is now. Back then we accepted differences, now, it's not OK. So I agree with you on that point.
But, things always spiral when there is no large middle class, when the wealth is in the hands of a few, and that is the most harmful thing that can happen to any country, not just ours.
