American history specifically around white people dressing in black face to mock and rob a race of people of their humanity.

Why would people be thinking about years ago in American history today ? Why when the people are not using it to mock people or rob them of their humanity ? Again simply dressing up as somebody. Are cowboys racist because in the Old West they killed Indians ? Or is it simply because they are copying the skin color ?

This isn't about being liberal or PC.

Well it's definitely about both. We are not talking robbing people of humanity. We are not talking about anything else but dressing up as somebody. The PC and liberal culture say if somebody is white they can't as a black person because some people's feelings will be hurt because they will be offended and taking offence. That is dressed up with the word racism. Are the movies White Chicks or True Identity racist? Again why is somebody dressing uo as somebody "bad" ? Because some people are still stuck on history from a long time ago ? Dont be done when you cant discuss something.
