There seems to be a bit of debate over whether the PUA (Pick up Artist) "community" is a friend of MRA's...
Now, getting over the sheer inanity of this question's face, it does expose a bit of a conundrum.
Do men REALLY want to understand women?
Many former PUA's will tell you that after a while they began to ask themselves "Is this all there is?" The ease of manipulation and shallow relationships, combined with the prevalence of women who respond quite willingly to this, tends to jade a guy.
Myself, I firmly believe that every man should read at least a few pieces from these "shysters" selling the Pass to the Golden Valley to the masses. They've got a lot of wisdom in them.
Mostly because they take a "What women DO, not what women SAY" approach to relationships, and many men need to get their heads out of their asses in these regards...and right quick if possible. I confess, I read and listen to many of these guys, and have utilized some of the techniques...frankly, they're generally right in my experience.
And you do get jaded quick. In my case, it was simply from watching my "mentor" do his thing...and he did it well. I almost immediately lost confidence in women's ability to "keep it in their pants" - ESPECIALLY when they are married or in a long term relationship.
As the saying goes..."Rings don't plug holes".
At any rate, the point is that once the majority of men are onto women's motivations, and call them on it, the more likely social pressure curtailing said behaviour is. Being angry about other's success with women, or refusing to do anything from lack of success on your own part, is counter-productive.
Knowing the wiles of the opposite sex has been taught to women since time immemorial, and lacking enough proper fathers out there to teach boys how to do this, PUA's will continue to proliferate.
One point made about PUA's is totally valid though...there are FAR too many of them that make getting laid the centre of their Universe. That comes from not listening to the rest of the advice, or failing to internalize that becoming your own man, with his own life that she can come along on if she pleases you enough, is the goal.
Not being an attention whore.
If I had to sum my position up, it would be that the quicker men internalize PUA stuff the better, but the more they follow the MGTOW attitude the better too.
Make women prove themselves to men, needing exceptional qualities in order to get laid / have kids, and you'll see a RADICALLY different society.
