" Not in our lifetime" is accurate IMHO.
Today's acceptance is not acceptance at all - it's a charade - the TG washroom is almost always segregated under the guise of tolerance - it is not the women's washroom.
If this was done because of another physiological reason - it would be considered an outrage
It's faux acceptance.
Almost all men who would show up en femme to their workplace would shortly be unemployed IMHO because their choice of attire makes others " uncomfortable".
Most of the sociological data shows few people are interested in true gender equality, for all our talk, gender roles have not changed much.
When it is legal for a CD man to use the women's washroom and it is accepted as normal - we will be on our way...
Men are still expected to be strong, protective and high wage earners.
