I've watched a few of the clips before, I've read a few of the articles, I get the gist of what it's about. The approaches, cocky/funny, project confidence, making her doubt herself to peak interest.
Even if I didn't, I certainly could comment on them anyway, but that's another issue in itself.
I think one of the reasons it gets bashed so much is because it gives people with little or no confidence, a big boost in false confidence.
I once read a book on human evolution, and when discussing sexual competition of our primate cousins, it said somethin' along the lines of: males that cannot provide what an alpha male can (strength, resources, security), will deceive females into thinking that they can provide those things so that they will mate.
I think any woman familiar with these methods would be wary of any guy who approached her with them. Assuming she wasn't already predisposed to suckin' dick that night.
