As far as I can tell, there are broadly three types of male bodied people who want access to female spaces such as toilets.
1 - transwomen. Are transwomen women? Should this be allowed? Unfortunately for these poor souls, who probably DO just want to pee, who probably ARE unsafe in men's loos and changing rooms, there are many more of the other two types of men:
2- autogynaphs, or cross dressers. These men are happy with their penises and male bodies, and are indulging in a sexual practice that is centred in misogyny. No, we don't want to share a loo with them
3 - out and out sexual preditors and abusers, peeping Toms, voyeurs, who now have unlimited access to vulnerable women and girls
Just. Awesome.
