I cleaned restrooms before, women's was usually much worse. Especially when ladies on their period. Disgusting.
I do support transgender people choosing their restroom. The birth certificate thing is non-sense as people can get it surgically changed after birth. Who's more likely to be assaulted in a bathroom, a woman in a bathroom with a MTF transwoman or a MTF transwoman in a bathroom with homophobic men? It was never about bathrooms as it was never about water fountains
