I don't care who uses what toilets but prefer women keep to their own. I'll keep short lines and a urinal anyday
However, once again, everyone is looking at it from one side. I will never let the boys go to a public toilet without being able to see their stall. If it is only me with the girls, we use the family room or disabled. I don't trust anyone in a public room with my kids, period. It feels awkward doing that in a guys toilet, imagine how awkward it would be in a unisex. I would be very concerned about a guy watching the stalls in a girls toilet for perfectly good reasons. Does this mean a guy can use the toilet at an all girls school? Where are the boundaries? Where is the "for the greater good"?
The bigger question is what damage we might cause to the majority for a very very very small minority. What does this do to potential rape or child sexual assault? Are all the proponents going to wipe their hands clean when a child commits suicide because they were molested in a situation caused by this? Is it going to be justified by saying that is stops committing suicide (as if the toilet is the only issue)?
The more enlightened people on here might feel totally comfortable, but that doesn't mean everyone will. Are you quite happy to sacrifice 10 or 100 or 10000 people for the one? If a reasonable solution can be found, go for it.
