The Onion

You're just choosing to be outraged for the sake of drama. I'm sorry if one person in your past has called you a "female" offensively, but lets consider moving on from it.

It's just a word. It's not a slur.

The word "woman" is not any better, and even has its own issues with preconceptions. Every time you come across someone who is trying to be stereotypically traditional and enforce any idea of classic societal gender roles, they refer to themselves as a MAN or a WOMAN.

Because I generally interact with people who are uncomfortable being assigned traditional gender roles, it's more comfortable to think of them as their biological sex--male or female, so that I am not projecting gender stereotypes on them

Now why don't you chill out?
