Too bad spectators like you are only here to downvote in disagreement, not giving any input.
A downvote is an input to the conversation, that's the point of the downvote. Not everyone wants to write an essay or argue with someone. Also what's the point of reiterating someone's else point, that's what the upvote is for.
You try to boost your score, everyone can see it, almost no one else do that. Have you tried not upvoting yourself?
Was my last comment boosted? You replied within ~10mins. But you're not wrong upvoting your own comment is a reddit hangover of having your own post automatically self upvoted. I still think it's a sane default. It's not about boosting my comments for visibility and rep points. Why would I upvote the only comment on a comment chain for visibility? If I was concerned about rep points, I would be commenting and posting more.
You almost always post/coment with an antagonistic approach. You're also so abrasive with how you communicate that it almost asks people "verbally" spar with you. I'm not just talking about this thread.
I think, I understand that you see all of this just as a conversation. I also respect that you don't downvote other people's comment that you disagree with. But dam everytime I see you, you're almost asking anyone to argue with you.
