What makes you think none of us have?
There is a difference between showing empathy/kindness when dealing with individuals on a personal level, and deciding matters of policy that involve many more than just that one person.
That is not what commonly occurs in this thread. Policy is being proposed based on personal feelings as well. Indeed, the tenor of discussion is people trying to reconcile emotions they have that they know are irrational when it comes to trans people.
But talking to a trans person, and really talking them is also two different things.
I offer an anecdote: Recently, and I mean within the last two months, a friend who is a young attorney who is a partner in a successful firm he founded, who is married to a beautiful wife, and is winning in my Law School FF League, came out of the blue as transgendered.
I had no idea. He came to my live draft in a dress. I was uncomfortable and shocked but did not show it. After the draft was over we had to address what the fuck just happened. I needed to know why he up-ended his life and ended his marriage.
After an hour of hearing what I had, it now seems so petty to have an issue with a lot of the feelings I had prior to the event even though I had known trans people as acquaintances.
New data, new positions. Do I still have some squeamish feelings about calling my dude friend her? Yes. But I recognize the illogicality of the emotion and the irrationally of my former positions.
