I spent a good chunk of my youth in a city that was so racist and biased, that it was one of the first in the nation where busing became mandatory. My first house in a "fringe area" (because it was affordable for a young single gal) had a race exclusion clause on the deed. 50 years later, my granddaughter exclaimed how 'open minded' the city has become by pointing out how her grade school touted their acceptance of non-white students. I'm sorry, but if you have to pat yourselves on the back for tolerating another race, you are absolutely clueless. It was depressing living there. When I visit there, the fact that neighborhoods can still be pointed to as Polish, Mexican, Puerto Rican, German, Jewish, Black etc indicates to me that people's biases are often generational and reinforced within families as well as on the job etc. No CE classes will likely fix that.
