I can’t say I never downvote anyone but I get into these comment chains from time to time where really no matter what I post whoever I’m talking to downvotes every response but I generally shy away from downvoting even things I dislike. I don’t want to fall into an echo chamber where all I see are only the things I agree with.
I will absolutely downvote some people I disagree with if I think they are making a bad faith argument or I think their view is bad. If the masses decide my opinion is wrong then it will work out in the end. If not, then it must have been a bad comment.
You are, I am, we are the masses. I don’t mind disagreeing with people. I would be more bothered to be somewhere where everyone agrees and we have a culture of chasing off anyone who doesn’t aka an echo chamber. I’ll downvote people being mean because we can disagree and have civil discussion. Also someone blatantly trolling.
