It might become more common, and besides, I don't have to only think of myself, do I?Actually trans people are fighting for (and in some cases, getting) their 'right' to use the facilities of their gender 'identity'.
This one is a more valid argument than you think.
Unless you actually catch them jerking off you can't do anything about it either.
Because what if they "really were" that gender, then you'd be seriously insulting them and depriving them of their rights.
All of this, is also saying that gay middle/highschool people can't go into there own love oriented locker rooms because they will be masturbating.
I can't help it. Stop oppressing me, check your human privilege.
If you identify as a dog, alright.
Then you don't have any human privledges.
