In general, I agree with you. But you can downvote for dishonesty in a comment, and the poster is advocating dishonesty. Not the same thing, but related. I think an argument can be made that that particular comment crossed the line and can be downvoted.<p>For example, you said that you believe a comment can be downvoted for being rude. I agree. But advocating dishoesty, I think, is far worse than being rude.
