Civility has become a cult.
Mods on modern websites (including Reddit and Lemmy.world) are forced to maintain courtly behavior instead of deciding who's the asshole. They will protect any cautious troll who can politely phrase 'you're subhuman and also secretly agree with me' but jump on the obvious reasonable response: "Fuck off." Even when that curt dismissal is followed by an explanation of how a comment was dishonest and manipulative, you said the no-no word, so only you get the boot.
And that boot will tend to be as heavy as possible, sometimes instantly permanent, because god forbid anyone learn anything. You keep permanently banning these trolls, when they can get a new account in minutes, and they keep coming back within minutes? Wow, it's almost like you've given them no reason whatsoever to stick out their ban and keep that username. Spritzing them in the face with a three-day time-out works better. This is basic Skinnerian conditioning - immediate reliable feedback is internalized and shapes future behavior.
It's not all that far from the truth. Calling out asshole behavior on certain communities has to be done with so much civility its as if you're just "agreeing to disagree". The courting of the fanatics on both ends of the spectrum is just allowing propaganda to flourish.
EDIT: To be clear, when I say assholes I mean the trolls who are knowingly and intentionally dismissing in your face evidence and trying to push some kind of narrative they feel is justified, no matter how heinous.
"Calling out the asshole," is a self-righteous way of saying, "flipping the bozo bit."

It does not add anything to be uncivil when calling out someone who might be a problem. That person is not the only audience. It still reflects poorly on one to act poorly, even if one convinces oneself that they have a "really good reason" to be an asshole to an asshole. And it assumes one's own infallibility.
Some people might like to see it and upvote it, but that isn't helping the interlocutor's implied intention of improving discourse. It's just creating a dunk culture.
When you see someone acting poorly, it's not at all clear calling them an asshole is a better strategy (even for one's own wellness, let alone that of the community) than assuming, hey, this person is in a shitty mood, and probably having a bad day; a compassionate person would offer them some help or at least attempt to be understanding.
It's hard, I know.
An asshole isn't someone who disagrees with you in this case. Maybe I should have pointed out that I'm talking about the trolls that exist here who are just assholes. It's someone who is intentionally and knowingly spreading out misinformation or cherry picked quotes and events to further an agenda. Someone who dismisses what they don't like to hear so they can stand some "authoritative moral high-ground" that they've made up. I'll edit my comment to better reflect what I was trying to say.
