You can't say that!

Interesting, actual conversation with my adult daughter the other day:
Me: the Negro people in America...
Daughter (interrupting): Dad, you can’t say “Negro.” It’s offensive.
Me:  Okay, the Black people...
Daughter: You can’t say Black either.
Me: Then what shall I call them?
Daughter: You have to say, “African American”.
Me: What if I’m talking about my friend Ed Zayzay, from Ghana. He’s not  American.
Daughter: You can’t mention race at all. You just have to talk about individuals.
Me: What about other groups of people?
Daughter: You also can’t talk about LGBTMNOQ people either. You can’t group people at all.
Me: What if I want to compare Republicans and Democrats?
Daughter: That depends. If you are saying anything bad about them, you can’t group people at all.

I must stress, this daughter is the mother of four children, is smart, and active socially. If she is repeating stuff like this, it must be common. How far we have come from, “I do not agree with what you say, but I will defend to the death your right to say it!”
