I'm fine with fun, for the sake of having fun. If that's already your personality, no hate. Do what you do.
But as a strategy "I'm gonna go out and tease women because then they will sleep with me" - I don't think it actually works on the general female populace (it works on a narrow type in particular cultures), and it causes people to presume that jerkiness is a desirable trait in human interactions. It's actually an arbitrary way of going through life, and a rather negative one at that. Many women (and also men) often get very turned off by the "playful insult" approach. Its no guarantor of social success at all.
If I had a choice between being with a partner where we goof around act silly and tease each other, and being serious, I'm going to choose the former every time. And clearly people are different. There's no one size fits all to anything in life, so I'd REALLY REALLY like to get past that, is that fair to say to you? So with that being said, I'm not so sure why you're arguing.
I'll repeat myself in case it was me that was being unclear. Tons of well adjusted people assuming they're single AND ready to date, meaning no traumas, no major mental hangups, no harsh feelings towards the opposite sex due to bad experiences... people who are ready and willing to date... TONS of them enjoy the teasing, the playfulness and the confidence.
So that being said, where are we at now? You can say "well yeah but plenty of people don't have this type of sense of humor" and that's all well and good. If we're playing a numbers game, since everyone is anyway in a sense, I'm going to make the choices that stack the odds in my favor. I'm going to develop my personality in a way where I invite positive happy and fun people into my life, and that's what most of these guys are doing.
I'm CERTAIN that if I looked, I'd find plenty of male oriented dating approaches that works for straight shooting gentlemen, but that's not necessarily playing the odds, especially in the way I see myself anyway, and doesn't attract the type of people whose company I enjoy.
And if you DO hate this stuff, well by all means call it junk and find stuff that appeals to you. Without checking at all, I'm sure it's out there and someone has monetized that type of approach by now.
But to say it doesn't work is stupid. It absolutely does work, on the type of people it's suited for. A lot of it has gotten really really good, and is great dating advice and material. And you only have to take it as far as you want to. Like anything else, keep what works and dump what doesn't.
Dating isn't a science because everyone's different, but there are practical approaches and if you want to develop yourself it helps to play in a way that gives you results for what works. And I'm telling you crystal clear, this stuff at least the more recent non-weird Mystery Method bullshit, is honest, helpful, and it just plain works.
It worked in the US, it worked in Holland, it worked in France, it worked in Italy, it worked in Croatia, it worked in Canada, my personality type has worked just about everywhere in meeting great women.
IT. WORKS.
