Yeah but in practice this isn't actually the case, people flag all the time for people just having a dissenting opinion, fitting none of the categories you mentioned
That one is arguably borderline—on the one hand, it makes large statements about a divisive topic without adding much information, but on the other hand it isn't snarky, name-calling, etc. I've turned off the flags.
There's one comment literally spreading misinformation and it isn't flagged, but instead got pushback by others, critically pointing the weakness of their arguments.
