Even though I don't agree with what this guy is saying I don't think this comment should have been downvoted, if you don't agree say so, downvoting is not for that!
Downvotes are "supposed to" be for comments that don't contribute to the conversation, not for a view that you disagree with. The only problem with this rule is that it is universally ignored. :p I got a billion upvotes on my original comment because people agreed with me more than because I was particularly insightful. I reflected upon this phenomenon here: http://twitter.com/#!/_sequoia/status/102066922274832384
