You're normally right, but.........
Rainboe - you are often, if not normally, right in your clearly expressed views.
I have to say that you are just plain wrong in this thread.
I know 2 pilots - one a Training Capt., and the other a moderately senior captain who have made the switch from male to female successfully.
I'm glad it wasn't me..........I would hate to be in their shoes, and I continue to wish them all the best.
If you don't like it, that's fine, but don't expect others to agree with you - you're just plain wrong.
