In another thread I said I'd met some trans scientists. People were very sceptical that such people exist,
Your memory of that conversation is inaccurate, I'm afraid. What you actually said was:
Last week I was in a GRA strategy meeting and round the table there were:
3 straight AFAB women
3 AFAB lesbians
2 nonbinary AFAB people
2 trans women
...and we were all in our 30s, 40s and 50s. Scientists, historians, sociologists, journalists
The only scepticism (which was actually ironic, rather than genuine) voiced was around how scientists could be supportive of the pro-self ID movement, not whether trans scientists exist. This was on the grounds that the majority of scientists are oriented toward believing in scientific fact, and thus presumably less likely to believe an individual can change sex.
