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.
Idk sometimes I’m reading a long a deep thread and someone who was arguing in good faith starts acting like a petulant toolbag. I will give downvotes then when they are 1-0, but I always kind of worry in the back of my mind that whoever I gave a downvote to will just think it’s the other guy. Other people read deeper on threads than you would think.
Personally I don’t see much point in voting either way in a thread like that. You’re using the vote button to express disagreement but you don’t have anything to say or contribute.
