Nooooooo. For goodness sake.
Ok so you are not alone. Other people on the course have witnessed and shared their opinion/observations. Hopefully you also feel fueled by the indignation of others here. And I can't think of anyone better placed to understand what you are going through than James Esses.
If I was being generous I wonder if the course leader is feeling vulnerable ... they are at risk of becoming a bit of laughing stock professionally...I don't know the circumstances in which they have shared their trans status ...this might once have been 'stunning and brave' but is now a bit of a credibility millstone.
Bottom line is you havent done anything wrong. We all need to engage with evidence and the absence of evidence.
Therapist the ass out of this meeting. Go slow, silence is your friend.
