The evolution of NoFap has been interesting, I'd always assumed it was a "Master of your domain" thing about proving to yourself that you were stronger than your base sexual urges, with maybe an element of tantric semen-conservation mystic woo retrofitted to it. But the full redpill narrative hooks it into this pseudo-scientific story about gender and evolutionary psychology, with testosterone taking the place of Chi energy, and serving as the root of physical as well as spiritual vitality.
It's quite neo-Victorian in some ways - Victorian masturbation panics were all about sexuality vitiating the health of the race, turning healthy males into vampire-drained, intellectually enfeebled shadows of themselves (while making women permanently-flushed hysterical nymphomaniacs). Like anti-semitism, it's really weird to see all that nonsense come back into fashionability.
