I don’t think this needs much elaboration.

I will add this, my own little comment about racism.  We shouldn’t use this incident to browbeat people into not saying things like this.  We need to remember this is about trying to get people to no longer think like this.  We have to be careful to tread the line between making people know that this sort of thinking is unwelcome, but not go down the road of bullying people to stop thinking that way, because it doesn’t work.

Live an integrated life.  Know people who aren’t like you.  Hang out with them regularly.  And then don’t think that everyone who is like them are really like them.

Maybe, one day.
