Actually I live in Canada, where the solution we came up with was “stop worrying about it.”
You know what happened?
Nothing. Nobody was assaulted and it cost zero people zero dollars.
But okay, the “in love with economics” Muslim woman says billions should spent across the United States so that she doesn’t have to share a space with those icky trans cooties.
Maybe you’re operating on a different definition of “smart” and “realistic.”
