The dating advice on The Red Pill boils down to "act like you don't care, and if at all possible genuinely don't care", which does actually work. It's the oldest negotiating tactic in the book. However they advocate being overly cruel and callous to hook-ups, like kicking them out onto the streets if they change their mind about having sex, the thinking being that allowing them to sleep in your bed with you encourages the formation of a bond that does not have a sexual component.
This has shades of the PUA fad that was happening a few years ago and I feel that an unhelpful amount of that baggage has been brought along, with men almost competing to see who can be the most clinical while having the most sex.
They also make some excellent points about divorce which any fool can see is an area of genuine institutional inequality.
But they are way too cynical about women, assuming they are all selfish materialists who care about nothing but themselves, and particularly extracting money and validation from beta males. This is plainly too simplistic: women do have integrity, they have the means to earn their own living, and in my experience they often take much more pride in their career than men, because women feel they owe it to feminism to be career-oriented.
However these laws need to be made equitable and until then their advice as regards this stuff could be useful for hook-up culture and relationships where there is a significant earning potential disparity and/or the female partner is desperate for financial support.
All in all, I think it is a much needed male space on the Internet. It unfortunately veers into misogyny and militancy relatively often, but I feel that it encourages men to define themselves on their own terms rather than according to what women want them to be. It gives men a point of reference for calling out unreasonable behaviour on the part of their girlfriends which would once have been available in male spaces like the local boozer. I think it's a positive sign that men are responding to the crisis of masculinity by communicating in male spaces, although they may be virulent, and hope that the men's movement snowballs and evolves like third-wave feminism into something more stable.
We must of course remember that feminism was just like this back in the 1970s, with many influential and controversial opinion-formers talking about an all-female utopia, violent retribution against men, all sex is rape etc etc. As feminism has settled down since, we can expect that the men's movement also will.
