No, because he THOUGHT it was wrong or misinformed. Large difference between something being wrong and him thinking it is wrong -- unless he is always right.

If something is factually correct, and he disagrees with it and thinks it is wrong, it gets a downvote. I was actually more amused that he got upvotes as it sort of reinforces the point I was trying to make.

By his logic, if we disagree with his point, we should downvote him, whether his opinion has merit or not.
