Should artistic works with specific executions be illegal and put the creative vision and writers in a mental hospital or in jail, just like anti-governmental political messages like Alice in Wonderland? Except in this case we tackle the entire execution and context, not just a few life lessons and moral messages.
Yes we'd have to jail the Canadians and everyone who ever worked on Cartoonnetwork and Nickledeon for promoting dumb shock writing. We'd absolutely jail people like John K and the faggot behind Fritz the Cat.
1) We'd have better cartoons depending on what standards are set
2) It highly depends on what standards are set.
You're still allowed to make dumb high school cartoons with awful teenager stereotypes, but you're not allowed any longer to create straightman buttmonkey loser characters UNLESS they're a DeeDee stereotype.
You're no longer allowed to create insane child masterminds, endless abuse of main characters and probably some very specific but very easy to detect executions like hypocritical contradicting messages and characters.
You're no longer allowed to create untouchable hysterically hateable characters like Q, Discord,Lizzie, Dolores Umbridge, Glimmer, Trixie/smug anime character #56,043 1) Because they're based on real people 2) Because they're genuinely disgusting people that should be sent to a mental asylum 3) They are self inserts by the writer or creative vision who thinks, believes, talks just like his self insert.
You are however allowed to create said characters if they get 24/7 their ass kicked, called out and are not treating as an intangible force of nature nobody can ever criticize.
