IMHO this cay acceptance crap will be resented just as much.
It was also during the 70’s for me.
We also had one on alcoholism. It was done by a Catholic priest. Surprisingly it was pretty good.
One guy in particular, a guy I walked to school with from grade school through Junior high, became president of the NAACP in the future. I rarely ran into him after HS, he was a very nice guy, but I swear to you that after that assembly he changed for the worse.
This was a kid that charged up the hill towards me and my little brother to confront us, because my brother had yelled down at them calling N....r n....r n....r, while he and his brother played football in their front yard. My brother ran home instantly, I stayed and apologized for my brother, told them I would pop him in the head, and tell my dad about it. We hung out and played ball afterwards. We knew that we had different color skin, but we treated each other like any other boy in the neighborhood. You didn't use the N word at all, mom would kick your behind, and they never called us whitey, honkey or cracker....until the day after the "assembly", then it was a common word.
Check my post 82 for my thoughts...
