“Get over it and go pee”

Alison Bechdel already knew the score in 1995:

The titular Dykes to Watch Out Fo are walking out of a bad movie, when Jillian has to pee. Mo, who has to do the same, doesn’t want to enter the loo because Jillian, though cool, is a trans woman. Lois tells her off, saying she’s not going to wait around all night just because Mo has a transphobia attack. So Mo enters the toilets, only to be challenged by a woman on whether she is in the right bathroom. (Mo looks rather butch after all.) Jillian defends her, telling the stranger to take a closer look. After this, Mo thanks Jillian and says she would do the same for her. This is however no longer necessary now her “nobody knows I’m a transsexual” t-shirt has worn out.

So there you have it, the absurdity of the bathroom panic laid bare in a twentyfive year old comic. Trans women are no danger, the idea that you can tell who is and is not a woman at a glance is deeply homophobic and barring people from pissing in the toilets they feel most comfortable in is ludicrous.
