I suppose anyone who uses the word "gay" as a negative in a sentence, such as "Man, these seats are gay. I can't even see what's going on!" (courtesy of UD), needs to be sent on these classes, we're going to have a lot of teenagers in a lot of classes.
Just because a phrase slipped down once doesn't mean she needs "re-educating". I've let a swear word out before when I've badly stubbed my toe in a location where swearing isn't ideal, but I know it was a dumb move and don't need to be "re-educated".
