>After engineering college I went back to school to get a degree in History, which I accomplished, with the thought to become a teacher. I graduated and at the same time the schools in the San Francisco Bay Area were letting go tenured teachers who were Caucasian, to give African Americans an opportunity to become teachers. That was 1975.

You have evidence for that last statement? Letting tenured teachers go requires some serious due process. Giving hiring preference to minorities, I'd believe, but firing whites to hire minorities seems really unlikely.
