Car pollution is an imagined complexity because other countries have simply adopted mass transportation.

There are millions of gendered restrooms today. It is an issue that has to be addressed by any law.

Okay, but so what? There are nuances involved in all policy implementation, that's not a compelling reason to oppose bringing it to the table. If it is offered in earnest (and I'm not convinced it is), it's reductive.

What you are calling nuances are major points though. At what point are you "identified" enough with your preferred gender to use that gender's restrooms and locker rooms? I feel no one want to pick a line because someone will be offended they didn't pick a more progressive line.
