Well, I did have a friend who announced ( or rather had his wife annnounce) that he was now a she/woman .

I had no problem with this: as far as I am concerned live and let live. If my friend felt more comfortable living & dressing as a woman then I had no issues with that. There was no problem for a couple of years until one arose when he/she expected me to accept the ideology that he /she with a penis and father of children was an actual biological female.

Unfortunately/fortunately for him/her I seriously dislike gaslighting and certainly dont intend to do it to myself to suit the psychopathology of anyone.
