I don't buy what they are selling either.
The manosphere has been around for decades.
It is the only place young men can come for advice that advances their interests first and foremost.
It has active debates on a wide range of topics.
It is way below the radar because the left has massive censorship against it—any mass media coverage is totally hostile, biased and inaccurate.
These are just normal guys trying to figure out what is going on with young women—and how best to deal with it.
Many of them do not have any father figure they can rely on at all—or their father is a useless wimp and/or a terrible role model.
The basic advice all young men are given is to get fit and look the very best they can—not crazy bodybuilding stuff—but just enough exercise so that their looks do not hurt them.
Then they are taught social skills that most women seem to understand automatically—how to read a room—how to tell if a woman is attracted to you or is not attracted to you—basic stuff.
There is nothing extraordinary about it—this is stuff that men’s fathers taught them over the centuries—but is a lost art these days.
