Pink guns amuse me.
I equate pink guns with The Vagina Monologues, odd as that may sound. They are symbols of that silly sort of feminism that insists that women claim things as their own, stand on the mountaintop and proclaim, "My vagina belongs to me! My body!", and "My gun! Girl gun! Pink! Hear me roar!"
What they don't realize is that these things were already theirs to begin with...
But... if a woman has been waiting for a "pretty" gun to become available before she was willing to shoot, then I'm all for it. Bedazzle the thing, trim it in lace for all I care, and let's go make some noise!
