Keep it real.

I'm a woman. All woman.
I've given birth to my children and breastfed them. I have periods.
I'm no stunner but I think I'm attractive.
I believe women around the world have a right to argue for their women's rights.
Men pretending to be women (let's face it, it's what it really is) shouldn't even begin to think they're anywhere near being a real woman until they've done the above three things in my post.

By all means disagree if you wish, however biological makeup are facts.
That you cannot deny.
