Yeah, but I think his point was that it’s very easy for white people to go on about how all men are created equal because that’s who the Declaration was aimed at.
It’s an uncomfortable thing to hear but this document was written by a man who held other human beings in slavery. If your ancestors were on the slave side of that equation, I imagine it’s almost insulting to have people go “Do we HAVE to mention this?”
I’m proud to be an American. That doesn’t mean I’m going to pretend the bad shit didn’t happen, and I’m not going to get bent out of shape when it’s brought up.
