Jennifer says he prefers the pronoun he, though whoever wrote the article used she.
Caitlyn, or Kaitlyn, is a nice enough name, more interesting than Katherine.
However, it's not a name a real 65-year-old woman would be likely to have; it would kind of be like a 65-year-old man being called Jayden. If Jenner wanted to be taken totally serkiously (though of course, this is Bruce Jenner we're talking about) he'd have done better to pick a name more in keeping with his age. Kathleen or Katherine, if he wanted to keep close to Caitlyn. Or Susan, Diane, Debbie, Patricia, Sandra, Linda, something like that.
I think, therefore I judge.
