I'm not sure I understand your experiment. You expressed the same thing three ways, so people clearly aren't voting differently according to whether they agree or disagree. They're voting on how you expressed yourself. Personally, I don't disagree with the votes much. The witty sarcasm has been up-modded too much, which is a problem on all sites, but it was the most concise and least agressive post.
