Don't worry about offending someone. That's what the interwebz are for apparently these days. Buncha pusillanimous individual PC friends are killing this country.
Also it's loving school. After you're done, there's a good chance that you won't even hear from 99% of those dipstuffs for years after you're gone. And those that do are the ones who actually liked you then and just found you after having a random thought of you over the years. Even then it's not guaranteed they'll keep talking to you other than just to say "hello, good to hear you're still alive and doing well."
