Liars, every one of them.
I know more than one guy who's had sex with some 100 women. In every case they targeted overweight, not-very-attractive women, because they did not care if the women got mad at them, ranted and raved, dumped them. They thought it was funny. They never told the women they loved them, because they were incapable of love (and that is the worst punishment of all).
What they told me, in every case, was that they told the women what wanted to hear. Except for saying they loved the girls. These guys are not "alphas." They're immature, insecure, narcissistic cads seeking validation from women - any woman. And they would have been devastated if an attractive woman laughed at them and rejected them.
I saw one in college throw a conniption fit when a woman he couldn't get dumped him for me. He was nearly hysterical, although being a coward he never said a word to my face.
These girls never had a clue. I suppose they were so unpopular than when some good-looking guy hit on them (the first one in their lives, I'm sure) they fell to pieces.
The same thing happened to me in college. I'd talk to some overweight, unattractive girl and her face would just light up. "A guy is talking to me!!"
I could have sex with 100 women if I had set my mind to it. But I never did, because the idea disgusts me. I have enough of a conscience, and enough guilt, to not target desperate, unattractive women because they're easy lays. I'm not all that much of a predator.
I still get women hitting me up on the street and in stores - single mothers and fat girls, overwhelmingly. Looking for a man. I'm not the one. They even ignore the ring.
These guys with the outrageous claims are doing it for money and attention. If no one bought their books and visited their sites, they wouldn't write books or, most probably, have sites.
Such guys reminds me of the adolescents I knew in high school. "I fucked this girl, I fucked that girl." No, you didn't. You're a liar.
Men are supposed to be protector/providers and women, nurturers. These guys are predators - parasites, which means they are anti-civilization. Imagine if every guy acted like that. Of course that's not going to happen, but if they did society would go straight backwards. In the not too distant past, guys like this knew they would be fired from their jobs and ostracized. That kept them under control and kept their behavior minimized.
I knew one player who got caught having sex with a woman he had hired. On company property. It wasn't his wife. He was a catastrophe in his job as a manager, and since he was working for a corporation it took four more years to get rid of him. He wasn't fired, just transferred out of state.
It used to be that if a man even got divorced his chances at promotion were gone.
The ones I knew did develop some charm, and were good-looking - quite extroverted, but disloyal, promiscuous liars. Some unattractive overweight guy is never going to be a player. That's a given. But overweight unattractive girls, overwhelmingly, are easy to play. Some guys know this and take advantage of it.
