You think kids will grow up to hate their parents because they weren't able to consume brainrot? They'll turn 18, open Tiktok for the first time and think wow our parents have been keeping this treasure from us all our childhood? Do kids grow up to hate their parents because they aren't allowed to drink before turning 21? If it's a general ban for all kids, not just some that will then feel excluded from the rest of the group, I don't think they'll care the tiniest bit about not being allowed to access this crap before age 18.
What could be great is a revolutionary generation. But I don't see that happening. We've already been dumbed-down, and indoctrinated into a selfish and therefore neutered culture.
More likely this will force them to be right wing as they get older. Young ppl arent digging left wing stuff as trends show many are shifting to conservatism.
