I didn't downvote you and I intend no offense.

Assuming that you genuinely approve of this article, a seal of approval from a user with 50% positive karma is more like an anti-seal of approval, regardless of the validity of that user's statements. Most humans will be inclined to smack you down for grabbing status that they don't think you deserve, and they may even improperly use the quality and content of your comment as a substitute criterion for evaluating the quality and content of the parent article. It's not to say that you should refrain from commenting at all, but that you should refrain from commenting if your comments lack cues that will lead readers to evaluate your comments and their parents slowly and deliberatively. The easiest way to do this is to write comments that can only be written slowly and deliberatively and to refrain from commenting otherwise.

Assuming that you don't genuinely approve of this article, obscurantism and social engineering are unlikely to be productive and are discouraged.
