A common argument to say that one should take downvotes as judge of content quality, not character, but it seems apparent to me that to judge quality is to judge character. I explain my argument below.
Suppose some person does some unacceptable act, then it is not possible for us to punish the act in itself. The act is done and is in the past. We can only punish the person, for be an actor of the past. If we punish the person as an actor of the act, that seems indistinguishable from punishing the person for themself. Or, should such a distinction be made, if so, why?
