I disagree. Downvoting for disagreement is a way of saving time in the discussion from reading lower value comments. To much low value content can mask more thoughtful discussion.
Just because I don't agree with someone's perspective, doesn't inherently make it low value or not thoughtful. I find I often learn much from people I disagree with, even if their argument didn't change my mind.
No the disagreement doesn’t make it inherently make it low value, and I personally don’t downvote purely for disagreement, but for disagreement with argument methods wether I agree with the positions or not.
