Nerds were often seen as poorly social since "logic and reasoning" would go against socially accepted norms. This where the fedora tipping meme comes from: "everybody understands that religion is not literal, but we have to all accept the lie for social cohesion". But "nerds" would be the ones willing to take the ridicule and ostracism because truth would be more important than conformity.
Reddit was the place to be for nerds and spread like a pandemic. However, karma points turned this on its head since you have a mechanism to enforce conformity in non-conformity that was the basis for "nerd communities". Nerds hobbies that would be the gateway are gated behind such platforms that enforce a social credit system in a totalitarian way. The would have been nerds are thus mostly integrated into the redittor archetype that is so fundamentally opposed to the nerd archetype; a contorted version of itself trying to fit through distorting mirrors.
I'm not disagreeing with you; but why did the nerds not destroy the ideologues with logic and reasoning if not for the horizontal pressure of other "nerds" subverting the concept?
