Teacher's 'terrorist' joke no laughing matter for student

Here is an example from one of my favorite bloggers:

Ugh. I'm still fuming about this. I host a poker game on Thursday nights and last night one of the regular players invited a new guy to the game that no one else knew. In the middle of the game, someone brought up politics (not me; I don't talk politics with most of that crew, I just play poker with them). And this new guy blurts out, "I can't believe no one has taken a shot at Obama. Can you imagine if they elect a fucking nigger as president?" I was absolutely stunned. I told him to get the hell out of my house, he wasn't welcome here. And then I got the typical answer: "Oh, I didn't mean...." Bullshit. Yes you did. You just didn't know it wasn't safe to be a racist around me. Now get the hell out of my house. This is not the first time this has happened in my life. It happened when I was in college when a co-worker said something similar. As soon as you tell them that you've got members of your own family that you love who are black, they always start to backpeddle. 'Oh, I didn't mean..." The hell you didn't. You meant exactly that, you just thought since we were both white it was okay to let your true feelings show. I've had the same thing happen with anti-gay slurs as well. Unlike most people, I don't just nod and smile when someone calls people faggot or other such slurs. While I will gladly fight for their legal right to say such things, I won't let it go unanswered and I certainly won't allow it in my house. And the reaction is the same every time.

Adrenachrome, is this not racism? Even in your definition of the word, does this scenario not epitomize racism? This is a feeling I'm sure many share. And this is a feeling they may shape the future of our country. Considering this, I can't see how anyone can claim racism is dead.

Ed responded exactly as I would have hoped, though!
