Dissent just means that one disagrees with what someone else has done or said. It doesn't mean to flame and it's got nothing to do with freedom of speech or a lack there-of. My original post consisted of 100% constructive criticism and nothing else, so in a sense, that is a motion of dissent against the suggestion.

By the way, your last post should have been aimed at codemastr so I claim to have been misrepresented.
