Nowadays people that say "DID YOU JUST ASSUME MY GENDER?" freak the fuck out and insult you. Then they go back to Tumbl and start posting shit about how society can't understand them.. Isn't the society beautiful?
Well, making up pronouns is kind of dumb. But wanting to be called "he" or "she" is not, I mean, you're not going to call your mom "he" (sorry, this is just an example, my respects to your mother), because she's a girl. Well, same goes for us trans. We just wanna be recognized as the gender we are. :)
It's not a big deal.
