I think that many men think that techniques taught by books don't really work in real life.
And others are just too lazy or too proud to change their ways to be more appealing to the opposite sex, and they assume that other people should be the ones to change to suit them instead (Many women also act this way regarding many gender issues -- it seems to be human nature).
And I think that some men have tried the stuff in the Pick-Up-Artist (PUA) books once or twice, found out that it didn't work on everybody (or maybe they didn't do it right, because they haven't practiced the techniques enough), so they gave up too soon, and decided that it just didn't work.
If you take all of the stuff in the PUA books seriously, it DOES feel like you are just putting on a circus act in order to impress stuck up bimbos with a short attention span. Many men feel resentment, and rightfully so, at being modern male "geishas" who have to be constantly entertaining just to win a woman's attention. Many guys wonder why they can't, "just be yourself", and win the girl.
Well, I always say that you have to meet people halfway. If what you are doing feels too unnatural, then you are simply trying to attract the wrong type of woman. You cannot please everyone, and you really don't want to, anyway, as many people aren't good for you in the first place. But it never hurts to learn some basic social skills so that you can interact better with people in general, not just the opposite sex. In the old days, before mass entertainment like TV and radio was invented, people wrote books on how to master the "art of conversation". Too bad that most people now-a-days have never heard of it, and don't know what it is.
