I'm very trans-friendly, and have a friend and co-worker I shared an office with 8 hours/day the whole time they were transitioning, which was like 2 years.
Direct quotes from a slack chat I had with Krista a month ago when she came back to work with us on contract:
"once i transitioned and life started making sense, the rest of everything in my head (mostly) just fell into place
i'm glad you were there and helping me out be being normal and not getting weirded out
that helped more than i could explain in an hour or two
(snip)
but having you around at work was very comforting and stabilizing, and i needed that"
I was thinking more of the circumstance where you're not at 'your doctor', perhaps due to incapacitation or bad accident you're at an ER type of thing.
I only said that out of concern for your care, not for the reasons this asshole is proposing this for. After further thought on it, if it's in your medical records, that's going to provide for the only concern *I* have in this regard at least in the vast majority of plausible situations.
My apologies in any case. I'm in no-way transphobic and please believe I'm on your side.
