Well, there go their college acceptances.
Wouldn’t bother me a bit. Back in the 1990s when the Malcolm “X” T-shirts were worn quite a bit, my oldest daughter use to wear a “you got your X, I’ve got my X” Confederate Flag shirt to high school from time to time. I was actually proud of her and most of the students did not care one bit. I certainly could tell that she was my daughter. :)
