I now wonder what I will do if I am ever in this situation. It's a true story BTW, told to me by a friend of mine. He went to his first college class in four decades, and this is the first thing that happened. He was so confused he broke out into a cold sweat and started to tremble. I think it's absurd, and it's suddenly happening in nearly all of the US colleges and universities. Private information. Maybe I would say something like "My preferred pronoun is the one you feel fits me." Oh and I'd add "I prefer my pancakes to have cattail pollen in them."
