I, at least, have different policies for "stupid" comments ("Ruby runs a hundred times faster than C!") and comments that present a valid viewpoint that is not mine ("Ruby is a cleaner language than C") - in fact, I'll upvote such comments if they are well-reasoned and on-topic. Of course, I'm not perfect.
