/u/LewisCross made an interesting comment below:

Sometimes you'll see very attractive men using TRP-style game. Actually there really is no "TRP-style" game. There's just "game". The reason people call it "TRP-style game" is because TRP writes it down and talks about it. Most men just do it after having received hands on, on the job instruction without anything written down.

The problem most people have with TRP isn't that they do it and put the precepts into practice. It's that they talk about it, write it down, share stories, talk to each other about how it all works, and explicitly teach it to less experienced boys and men, in full view of women, on the internet, where everyone can see and read it. This kind of instruction used to take place between men and boys, in private, and it was usually pretty much done by the time the boy was at the mid-teens. By the time he could drive, the boy had a good working knowledge of female nature, as taught BY MEN to boys. And women were NEVER around even so much as to watch the process, much less take part in that process and have a hand in the instruction.

The reason Blues don't like seeing this stuff is because it skeeves them out reading about men learning this stuff, in public, on the internet. It horrifies women, because, well, it's true.

1: To what extent was TRP-knowledge passed down from man to boy in the past?

2: At what level of detail was this done? Was it just basic advice like "don't be a pansy" and "be confident?" How far did it go?

3: What actual evidence is there that this intergenerational transfer of knowledge that /u/LewisCross describes actually took place?
