For the most part, the letters in response to Matt Landreman’s Opinion piece were appreciative of it, as am I. But then the political-correctness carping about wording began.

After awhile, I have just had enough of all the present-day quibbling about political correctness. When I was in graduate school, at two different universities, I had a number of instructors and professors whom I personally felt were a bit rude, but I found absolutely no correlation between that and the amount I learned from them about physics. As a result, my tolerance was more than amply repaid, and I’m sure that in a lot of cases, I was the recipient of their tolerance as well. Polite tolerance is the lubricant of social interaction, so I’d like to see more of it, not less.
