This really is disgusting.

People, including me, have a tough time admitting he’s not wrong. But as a gay man, I saw myself go from being classified as gay, then to LGBT, then a mishmash of initials that attempt to categorize me into a bogus group to which I do not necessarily belong. Personally, I resent it.

I think the “one of my PhD students” line disqualifies you from making a valid point. Did you have to include this unimportant, uninspiring bit of elitist information?
