Forget about "danger" how about we simply respect those who are not comfortable with having the opposite sex pissing or perhaps exposing themselves right next to them ?
How's that going to happen?
There's things called stalls that prevent that or are you ignorant enough to think there would be urinals ?
If it's a large public rest room, I would expect the business to accommodate the needs and wishes of men.
Besides, like you said, if it bothers women or tranny's that a man is standing at a urinal pissing, they need to get over their immaturity.
There are no urinals in a unisex bathroom problem solved.
Wait, why is that solved ? If it's a small public rest room then I'm used to seeing no urinals, but if it's large and busy then there need to be urinals in order to speed things up.
Besides, we now live in this world where according to you people need to get over their immaturity, and just expect to see the opposite sex pissing now and then.
If it bothers women and tranny's they need to grow up and get over themselves.
