This is one example of countless other objections that are leveled against PU that fall into the same pattern: an elaborate argument is presented that illustrates a problem with PU and yet at the same time it is overlooked that the same argument could be applied(yet rarely or never is) against women or against dating/mating in general. Specifically:

Of course, if you think a woman's welfare is her own problem and an interested man's only responsibility is to be attractive to the woman then you won't find this compelling but that attitude is precisely what the problem is (many people think that one should be concerned about the effects of one's interactions on others' welfare).

and:

I say the problem is a lack of concern about the welfare of women.

The name of the game is mating, not altruism! In mating we are generally not concerned primarily about the welfare of the object of our desire. It doesn't matter if you are human, non-human, male, female, homosexual, heterosexual, PUA or not PUA. Is a woman who expects the man to pay for her drinks, or the boyfriend to help her pay the rent really concerned about the welfare of the other?

Doesn't sound nice, does it? But I didn't write the rules of the game. Actually it should be a big surprise if the mating game that came about through evolution conformed to our expectations of fairness or niceness. PUAs didn't invent the game, they analyzed it and figured out what the winning moves are. Don't blame them. This is actually what all the PUA hate is about: rationalized or cleverly packaged envy. Those guys who figured out how to hack the system imposed onto them and gain an "unfair" advantage, we can't let them get away with it, can we?
