If someone says Hey, this hurts people and promotes racism, and maybe you ought to rethink it",

Yes, the word just might mean something else to you and others who share your lack of experience with this word as a weapon. But for something as serious as racism?
Maybe you ought to consider that the people who will suffer from it and have suffered from it just might have a point, okay?
The only way to stop it is to be an active and willing participant of stopping it.
Cluebat over. Think about it, all right?
