Another simpleton expressing a simplistic opinion.
You don't have to cut yourself down so much.
Bathrooms are designed to accommodate physical differences between men and women (i.e., urinals).
Irrelevant.
In unisex bathrooms you can have both urinals and stalls. There is no rule saying that urinals have to be exclusive to men bathrooms.
In addition, the vast majority of women prefer same-sex bathrooms.
Argumentum ad populum.
Their opinion is irrelevant. What is right is not determined by popular consensus.
Men who want to be women can still enjoy the privacy of a toilet stall in a men's bathroom (and women who want to be men can try to use a urinal), so what is the problem and how will expensive individual unisex bathrooms solve it?
Follow the OP mate.
I am arguing that all men and women should use the same bathroom.
