I can’t believe intelligent people, presumedly, are refusing to see the ramifications of this and are pretending that it’s no big deal. It’s exactly what you said, facilitating perverts. And they don’t have to be trannies to use the same bathroom as women, they can just “identify as a woman”, and I doubt of some wanna-be pervert claims to be a woman, any of the SJW-supporting businesses will take it upon themselves to require official proof. So, free-for-all for the perverts.
