...A Better Idea....
Actually, this is not a new idea. There are bathrooms like this all over the world. Why are mentally defective people wanting to all of a sudden, these years (2015-2016), having trouble deciding what sex they are and where they want to use the bathroom? There have been people with sex changes, and transvestites on earth for a long time. Why is it, a public bathroom now seemingly appears to be a problem for these reprobates? It wasn't a problem years ago.
And, more importantly, why is an ungodly (so-called gov't) government on their side??? Well, that's obvious, they are an ungodly beast system, have been since, oh, the 1700's (USA)....it's just now coming to a head...and speaking of head' urinals on the left for those who can just "whip it out" and the right; other side "toilets" for shall we say, the required "sit down" method for either and or. :) There! Problem solved for the 3% of the U.S. population that have a hard time choosing the proper sex-oriented bathroom.
One more note, no matter what people do to their bodies, what clothing they wear, or how they feel- these mentally challenged people will never fit in with the normal society; but....the above restroom modification just might help and solve the societal confusion and bring some physical clarity as to where those people can physically and anatomically take a "wiz!"
