I don't think being contrarian is a requirement for seeing value in comments that others disagree with. Just on this thread, your comment was downvoted but represents a particular way of solving a problem that differs from the downvoter's. Even if that way is not better, for them, I think acknowledging that it might be better for someone else is objectively open minded, and not in the least contrarian.

But my point isn't to criticize anyone for downvoting. Just the opposite. It's to illustrate that thinking outside the box is in itself disagreeable, which, as is the case here, can be a searchable metric.
