If I say I disagree with someone of course I am saying that they are wrong. Just as they are saying that I am wrong. That's what disagreeing with someone means.

But saying someone is wrong isn't the same as saying that he or she is a bad person, just as saying that someone is right is the same as saying he or she is a good person. Some of them are and some of them aren't, both ways.

But that's the line that is being crossed in a lot of the public dissent we've been seeing. It's the kind of thing that was happening in the election when John McCain felt it was his duty to rebuke people who were talking hate talk. And the shameful thing is that there doeesn't seem to have been something similar this time.
