Why are women so negative about the "pickup artist" community?

I became negative about it because of what I saw it do to guys.

When I first learned about it, I was mostly just intrigued. I ended up learning a bunch about it. I read The Game: Penetrating the Secret Society of Pickup Artists (which I still think is a really interesting book) and ended up meeting a lot of people who were in the pick-up artist community (not a goal—it just happened).
