There are 278 babies born every minute. 2-14 of them are trans, depending on various estimates. Every day, it is likely that someone is born who will one day grow up to have a gender unlike that of any living person, even if they are never exposed to the right culture and information to find this gender within themself.

I was graduating college in a liberal town

“Bro… 10% … of all… mammals… are, so to speak, ‘gay’”
