Mistee,
I think you raise a valid point. As much as it doesn't seem like a big deal to many of us older folks, I have had some conversations with my 20 year old daughters about this. It is a VERY big deal to them. This practice of referring to someone who has transitioned by their old name is called "dead naming". While I'm sure that none of us mean any disrespect to Wendy or any other folks in the trans community, by todays standards we are unknowingly "stepping in it" at times. I am regularly talking with my daughters about this ( one has TWO trans roommates), as perceptions and accepted terminology are changing very rapidly. I hate the idea of offending people, but it does happen by accident from time to time. I have no idea what Wendy would have to say about it, as from what I understand she values her privacy and doesn't seem to comment on these things much.
So anyway, not wanting to be any kind of snooty intellectual or know it all, but wanted to pass along what I have been hearing from my kids. I personally, have no clue on these things and need my daughters to keep me informed. Peace on earth, and good will to all folks.
