I agree, Kitrah, if I had just told him that I'm trans. But I had done it earlier, he'd provided his support via email, and earlier in the dinner told me that he'd told his parents who knew me well when I was a child and in high school. His father remarked that I'd make a pretty woman - which was a big surprise! I thus think that his "genital mutilation" comment came from what he really thought although it wasn't given with any disdain or negative baggage. He did respond to my email and apologized, saying that his ignorance was really on display. So, we're all good!
