I Am Going to Say Something Controversial
The whole trans washroom issue comes down to this: Men are a danger to women. Some women don't want transwomen using the ladies' room, because they think a transwoman is basically still a man and therefore dangerous. Many transwomen don't feel comfortable using the men's room, because men are dangerous to them. If men would unlearn their violent habits and treat women with basic respect, nobody would care who uses which washroom.
