Also, literally who cares. This isn't politics. Zoomers and millenials are very left-wing and that hasn't changer significantly in recent years. This isn't happening at scales that are shifting the political landscape. Idk why there is an obsession with this shit.
So much of self-help is one-part Do The Obvious Thing (hygenie/appearance, manners, social outreach) and one-part Weird Superstitious Bullshit (mysticism, mantras, arcane dietary habits or abstentions).
The first part is marginally helpful, but still requires you to get out and practice socializing. The second is pure placebo, intended to juice your convince and set you up for further fleecing with "magic extras" that the Guru will try to sell you.
I agree Leftists would do well to adopt some of the Self-Help methodologies, simply because they're proven successful at building movements. At the same time, the last thing anyone on the Left needs is more Personality Cults and highly orthodox social cliques fueding over which set of Magic Beans will bring FALGSC.
and nobody ever explains how to do this without bothering people. The rightwingers don't care if you make nine women uncomfortable to find one who is receptive to their bullshit, and the mainstream-to-left feminism stops at "leave women alone" because they're understandably not focused on that side of things.
This is why America is flooded with cults, gurus and "rehabilitation centers" which are just fancy prisons.
