Following a streak of bad press from overbearing policies, like cracking down on "fake" Facebook profiles –- which overstepped into the transgender and drag communities –- Facebook now offers a "custom" gender field.

It wasn't until 2014 that it even offered gender-neutral options, which would change the pronouns associated with your name; write on friend's wall for "their" birthday, for instance. 

 The pronouns still appear as a him/her/they dropdown.
