I don't agree with this comment at all. Skepticism isn't denying the claim or advocating an alternative one, it is promoting thoroughness and responsibility. The uninspected claim is quite a bit more dangerous.
This particular flavor of skepticism does not promote thoroughness and responsibility, in fact it promotes laziness: "Why read (or even skim) through the article when I can just state these five ways in which the article might be bad and therefore its argument void?"
