I feel people have been too trigger happy to defend Obama against everything on the internet; he's been smeared by unfair attacks on the internet, probably moreso than any of the candidates, but at the same time, some people seem to be going overboard in their vigilance against smears that they confuse what is a smear with legitimate criticism.  The guy does a pretty good job defending himself without this unneeded protection; he wouldn't have gotten all those votes and leading McCain in the polls if he couldn't speak for himself.
