And you don't think there will be any problems if someone who outwardly has male features (e.g. a beard) walks into a female bathroom? Everyone will just be fine and say "Oh, they are probably transsexual, no worries"?

Many women have hirsutism, most often due to hormonal conditions like polycystic ovary syndrome. They continue to use the female bathrooms without issue.

No, they are not "without issue". Since the trans discourse has picked up, there have been many cases of these people being targeted and attacked due to "using the wrong bathroom".

Nope, this is a myth perpetuated by activists. Even if there was an isolated case of this, it's not a general rule. There is more chance of being struck by lightning, but that doesn't stop people walking outside.

Really, you're resorting to that excuse? I could show you examples of such cases, but there's no value in doing so, since you've already declared me wrong and them to be isolated cases.

Exactly, the vast majority of people aren't so stupid as to believe that a woman who has grown some facial hair has somehow become a man by doing so.
