Re: Detail?
It's a law about toilets.
As you know, 'Murican toilets are surrounded by a screen starting no less than 120cm from the ground, making the toilet (which they call a bathroom even though there's no bath) essentially public space.
This is partly modelled after the Roman design of toilet, where everyone sits in a row, making shitting a truly social event. That and they're just too f'ing mean to buy more chipboard, as evidence by their "cubical farm" office design.
Anyway, when you combine this "ethnic" toilet arrangement, with latent religious fuelled LGBT bigotry, simply taking a piss becomes a hot political issue among fat faced 'Murican legislators.
On a separate issue, a bunch of corps like PayPal are jumping on this for PR reasons.
