Ah, you've run into Roissy, or people inspired by him, haven't you? No wonder you have such a low opinion of the motives of PUAs.

Roissy started a network of blogs combining pickup with conservative (and often misogynistic) gender politics (for instance, he seems to condone slapping women). Although Roissy has succeeded in repackaging common pickup advice for mass consumption, he is not an important figure in the seduction community. While there is enough pickup theory in his writing that I can't say that he isn't a pickup artist, he and the community around him are not representative of PUAs in general. I'm not going to say that you won't easily find misogynistic beliefs among PUAs, but it's just not typical for PUAs to resent women's right to vote, for instance. There are plenty of liberal-leaning PUAs.
