I was in favor of unisex bathrooms, but someone pointed out that women are constantly harassed by men and the only safe way to escape unwanted attention is to retreat to a place that men basically cannot enter.
That is, it can be unsafe for a woman to tell a man to leave her alone, or that she's not interested, or similar. She can go to the bathroom though.
I don't know if it differs outside of Canada but "unisex" means single occupancy just like a toilet at home. Where TF are unisex bathrooms where both genders collect en masse a thing? That's just asking for sexual harassment.
Some workplaces have "all gender" restrooms with multiple stalls. Intel is one. Men and women can use it, but IME I've only ever seen men use it to poop in peace.
