Yeah, I'm in the same camp. Big on sports as a kid and in high school and never thought twice about using "fucking faggot" or whatever as a pejorative. Changed my tune when one of my good friends got hospitalized by some assholes because they thought (rightfully so, as it turned out) he was gay. Seeing a D&D buddy laid up just for being who he is - not hurting anybody - changed my perspective 180 degrees in an instant. Did my best from that day forward to keep from slipping.Although this might seem like a harmless joke to many I can easily see how things like this add up to create an atmosphere of hostility towards gay people. I do hope you made it into a learning experience for the students so they don't just feel like they are constantly being monitored by the "PC" police. If they don't understand the consequences they're not gonna stop. It's taken me a long time to stop saying "that's gay". I used to just avoid it around gay people but I've learned that's not acceptable either or right.
