"Choice" Architecture, Nudging, and "Gender" "Neutral" (i.e. Sex-Integrated) Public Restrooms

The internet has defeated me at last.
This is satire. I know it has to be satire.
But some of the links that I thought constituted winks and nudges are themselves either nutty or deadpan satire.
Honestly, I gotta have some help here. Somebody please tell me for sure that the page on the other end of that link is not serious.
You win this round, internet.
