The worst comments are of the "just asking questions!" type. The asker will preface it with an apology about them being "genuinely curious", and then continue by stating their "concerns" about how the established and agreed upon consensus was reached, and say they "couldn't help but notice" how the "other side" gets "suppressed/censored".
This type of concern-trolling is straight out of grassroots propaganda rulebook (which the asker is either consciously following, or has been a target and victim of themselves), and it's quite depressing how many posters here fall for it and engage the asker in good faith.
I recently learned that some people call these comments and posts "JAQing off"; such a term isn't going to change anyone's mind, but at least there's something to sadly smirk about when I see the same bad-faith questions posted for the umpteenth time.
