Posts telling parents to make their kids drink bleach or disinfectant is, sadly, not actually a caricature. See, for example, how "Miracle Mineral Supplement" (aka, chlorine dioxide, aka bleach) gets pushed by malign quacks as a cure for HIV, malaria, hepatitus, autism, acne, cancer, COVID-19, etc. https://en.wikipedia.org/wiki/Miracle_Mineral_Supplement
This one gets harder as who has the better/right-er numbers? Is Bolosonaro lying? Probably. But how do you tell? Who's fact-checking the fact-checkers?
But the clear-cut cases aren't actually the problem. You don't need to censor things that are so obviously stupid. The bottle of Lysol says things like "Hazard to Humans and Domestic Animals" and "call a poison control center" etc.
To the point that it's incredible that the few people who actually do it are even telling the truth about why, instead of being cases of insane parents looking for a cover story when they want to murder their kids, or Munchausen by proxy or something like that.
Meanwhile the same principle gets you absolutely nothing in all of the non-obvious cases, because when the answer is non-obvious (and therefore much more problematic if wrong) then Facebook doesn't have it either.
Maybe he is, but if a system is to function properly it must work in the worst-case scenario.
Therefore, I disagree that this person is arguing in bad faith and is in fact attempting to point out where the system fails in a worst-case scenario such as this.
