PUA... why the sexism?

When I first picked up Neil Strauss' THE GAME, I knew I was tapping into something much larger than a simple guide to getting laid...

It was a roadmap, the ULTIMATE self help guru book to learning self confidence and self worth. The basic understanding one could and should pick up from this book, are not tricks of the trade, but rather how, once you're confident in who you are, people are naturally attracted to your own self worth.

That said, it goes back to the basic feminist argument, why are men players while women are sluts?
