Point: imposing value judgements (especially if enforced), weird shit like it being ok to show hundreds getting killed if there's no blood or cursing
Counterpoint: some kids are pussies (like me) and will be traumatized by gore and violence and shit
Countercounterpoint: kids need to see that violence to prepare them for revolution or something
Maybe something more akin to a list of trigger warnings, or the IMDB parents guide that just described all the acts of violence/sex and instances of cursing would be more helpful and value-neutral
