Purity and Individualism
The race doesn’t care about drugs or fapping, it only cares about whether you uphold civilization and reproduce the race. Thus universe doesn’t accept any excuses for failure or give any bonus points for supererogation.
Due to the ideal of the Renaissance man and the radically individualistic notion that heaven and hell are the only outcomes, there is this faggy experience culture according to which people are judged by how much experiences they accumulate. Obsessing about purity isn’t countersignaling it, it’s simply the reverse and no less radically idividualistic, replacing degenerate experiences no one cares about with supererogation no one cares about.
It’s worth noting that regarding sex, for men there are three reasons, to cement the pair bond, to reproduce, and to get notches to brag about. For women there are only the first two.
