Well, if society is going to pretend that homosexuality is normal, then only two possibilities for restrooms make any sense: Either one restroom for everyone or 4 different restrooms (Men, women, gays, lesbians).
Ask yourself this, "Why do we have separate restrooms for men and women in the first place?". Because women don't like to be gaulked at or propositioned to while they're straightening up their underwear with their skirts pulled up. Well, I'm a man, and I don't like to be propositioned in the men's room either (though this has happened only once).
If I had a restaurant, I'd have the 4 restrooms, just to piss 'em off! Of course I'd be sued, because someone would find a way to be "offended", meaning, liberals would claim a way that THEY should be able to control that aspect of our lives as well.
I remember working in Atlanta in my younger years. The Manager positioned me beside the Ladies restroom and said ... These Gay dress like Women, but they aren’t, and attempt to go into the Ladies Room. Keep ‘Em Out! I replied, *Yes, Sir!* I check everyone dress. Just kidding about checking every dress.
Weird. Going on by that logic, you need either three or infinite restrooms. One for men only, one for women only, and the rest can only have, max, a xx-weirdo and a xy-weirdo at the same time each, because any other combination implies improper company in the same room.
Then again, I’m using “sane people” logic here, there’s no reason why it should be even applicable.
