I have no problem with an argument about why you shouldn&#x27;t believe something. I <i>do</i> have a problem with &quot;vacuous skepticism&quot;—a comment saying purely &quot;this is doubtful and I remain skeptical&quot; is the photonegative of a &quot;this&quot; or &quot;me too&quot; comment: a way to say &quot;I [upvoted&#x2F;downvoted] but I also want to say words to the same effect to call attention to myself, without adding anything to the discussion.&quot; It&#x27;s an applause light; a magnet for upvotes from the same people who voted in a given direction on the story itself.
