Lets see...

My grandmother shot competitively in college (that's how she met my grandfather), and considered M-80s good clean fun.

My mother taught me how to throw knives.

My sister comes up to my shoulder and when we spar she throws me around like a rag doll. And I'm neither (a) going soft nor (b) untrained.

I do NOT, repeat, NOT discount women as being dangerous, scary and just plain able to kick my butt.

And when my DGF is made at me, she makes tofu, and gives me The Look until I eat it. She's mean.

EDIT:

I forgot to mention a female friend who is a Gaurdsman. She's a trunk monkey, and she thinks AT-4s and Claymores are "cute". *shudders*

YES, I KNOW SCARY WOMEN!
The worst danger is if you hurt them, I would be very, very annoyed with your existence in my space-time continuum.
