The thing is, if you're not depicting "the outcast" as being a pariah for unfair reasons (being fat, autistic, poor, non-white, queer, mentally ill, etc) then it just comes off like they're an outcast because they're an asshole who thinks they're better than everyone else
Hardly the first one to bring it up but an issue with a lot of larger studios doing "The weird outcast" kid trope is how they strip the politics away from outcasts
Aspects of race, sexuality, able bodiedness etc are removed to be as marketable as possible now
