I agree with you, but I still down voted your infomercial comment because I felt it was childish and added nothing of value. It has nothing to do with whether I agree or disagree, but the whether the comment adds to the conversation. Granted, most HN users these days don't follow that rule. They'll down vote purely based on whether they think you are right or wrong. But in this case, your comment didn't contribute anything meaningful. Maybe you thought it did, but as someone who agrees with your sentiment, I felt it didn't and down voted accordingly.
