So are you suggesting that they should be forced to allow transgenders in the locker rooms, regardless, or no?
Well, in my opinion, if you have a penis, you should go to where the 'penis' go.
I'm not sure what the 'Law' says.
If you have a 'Members Only' establishment, you can pretty much write your own Rules.
If you have a 'Public Facility', you're at the mercy of whatever the State Rules are.
