Here he is actively flaming/trolling in Main Community and Agora. He even states he's willingly losing sleep because he likes arguing so much. Just because the person you're disagreeing with is being salty doesn't mean you have a free ticket to stoop to that level. It's not moderator-worthy conduct.

That's a bad faith interpretation of my comment. Note that I did not link to every single instance of him being against defederation, as the issue isn't him stating an opinion. The problem is the sarcastic and aggressive way in which he chooses to interact with other users; sarcastically calling for defederation from lemmy.world because he saw a racist meme, and stating that he's up at 3am losing sleep because he loves arguing with idiots.
If you are being flamed, you report. Stooping to their level makes you no better.
