I've already run into multiple people on Lemmy who do what I call the Reddit Special:
See an opinion you don't like
Intentionally misinterpret the point to mean something else and attack that
Support your opinion by arguing backwards from your conclusion
Ignore all counterarguments when possible, return to step 2 when not
Try to "win" with pithy mic-drop bon mots at the end of your comment
Mask upset feelings by trotting out overly slangy 2am Chili style dismissals
For example a conversation I have actually had more than once on Reddit:
Person 1 - "I hate the designated hitter in baseball, it was more fun before, without it"
Person 2 - "Why are you in love with the old days so much? Do you want segregation back too?"
Person 1 - "Are you crazy? I just like it when pitchers bat"
Person 2 - "Lol. Clearly you have issues with being called out on your bigotry"
Person 1 - "You're not listening, I said I like baseball better when pitchers bat"
Persot 2 - "lmaoooo I don't listen to racists"
How about we have a mechanism to reward people who contribute constructively to a conversation by giving readers the ability to mark them as positive or negative? You could then provide an overall score - let's call it "karma" - to show whether they're good or bad members of the community.
Oh, wait. Yeah, that really didn't end up working like that...
