I agree - although name calling is not (or should not be) a punishable offense. I didn't get from the article exactly how he used the term; was it a chat forum or what.
He also committed the offense of opposing a Gay Straight Alliance group, so people were probably on the lookout for hatespeech crimes.
I concur. He made the comment on an online forum not related to the university so he should be able to do that without retribution... unless he signed something preventing him from openly expressing himself when he joined the Catholic university. Other than that, I can't see the university having much of an argument.
If only Miner knew the benefits of diplomacy before he expressed himself...
