So the feminist author had a look at Mystery Method from a biological, cultural, rhetorical and scientific viewpoint.

She should have had a look at it from the viewpoint of practice, because that's the only one that counts.

Does Mystery have success with attractive women? Yes. Does his Method contribute to that? Probably.

I don't really see why feminists worry at all about PUAs. Most feminists will not get approached by PUAs anyway. They shouldn't care. And we shouldn't care what they say.
