The "they're already doing this" fallacy. Reminds me of pushing homosexuality (or sex in general) on kids in schools then pedophiles turn around and say kids talk about it themselves.

"Kids already watch internet porn so googling the word "titties" will be detrimental to their development unless we indocrina.... teach them about grown ass men buttfucking little boys and spread literal child pornography is schools"

They ALWAYS use this tired dumbass argument. "We already do x, so why are you upset about y?"
