re: It looks like I'm heading to a university disciplinary review board....

I am in one of the last great untamed wildernesses of a workplace where I say "frick you", you say "frick you too, a-hole" and nothing happens at all. No sensitivity training, no meeting where everyone jerks each other off, no apologies, no nothing.

It goes to fist city sometimes, we break it up, tell the parties involved to knock it off and that's it.

In saying this, I'm probably not the person to take advice from here but don't make apologizing for something you aren't sorry for a habit. If the review board starts trying to spoon feed you a mouth full of bullshite, tell them to get fricked and don't have any regrets about saying it.
