There are cameras everywhere we go. Infringing on our privacy is public policy these days. As far as video taping in restroom goes, it would depend on the intent of the recording. If the purpose is to intrude on a person's privacy then, no, it should not be done. But if there's a freak in the bathroom and he poses a threat to the women in the bathroom, then I see nothing wrong with exposing the danger.Had she just made a vireo objecting to the trans her membership wouldn’t have been cancelled. She video taped someone in their locker room. A clear violation of their policy. Are you in favor of having people videotape others in a locker/changing room?
As to the backlash. Good vote with your dollars support businesses you want.
There should be no need to lie about what happened.
