The intent of graying comments is to deemphasize them and mitigate bandwagoning.

I do wish a 0-score would not show any graying though, in the case where this is an errant downvote.

How does graying comments deemphasize them? It results in a different appearance which makes them stand out. Surely the optimal way to deemphasize something is to make it the same as everything else, almost by definition?
