>>Possibly I would be annoyed if the mens restroom gets crowded with woman blocking the sink to put a new layer of paint on too. Doing the chatter. Can do without.
There won't be a mens', there'll just be a queue for "the facility." Not entirely new: toilets on aircraft are unsegregated and the world doesn't end.
Perhaps the next complaint will be that men sharing the facilities don't put down the lid or (worse) don't bother to raise it!
FWIW, it all seems to be less serious elsewhere- even politically correct pop stars participate in the fun. E.g. see this Sting concert on his US tour (and check out the audience) :

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
