Exactly.
To quote John Oliver:
It is so much easier for everyone involved when you're allowed to use the bathroom that matches your gender identity, rather than one that matches the genitals you were born with..... that is why the little pictures on bathroom doors are stereotypical representations of men and women, rather than biologically accurate depictions of penises and vaginas.
And look, this is a civil rights issue. And if you're not willing to support transgender people, for their sake, at least do it for your own sake. Because, we've been through this before, and we know how this is going to end, if you take the anti-civil rights side, and try to deny people the rights that they are entitled to, history is NOT going to be kind to you. There's no biopics out there, where Liam Neeson kicks the shit out of a suffragist, there are no stamps featuring George Wallace at the schoolhouse door, and YOU are NOT going to get a monument that says at the base of it: "You told people were to shit!"
