That is, after all, precisely what unsubstantiated means.
Which is why I commented at all, being tired of commentary that simultaneously complains about either the low quality of current comments, or the impossibility of high quality comments --- while at the same time providing negative value itself.
Your approach is a variant of the tired formula "The post is [stupid/terrible/useless/...]. I am obviously [more knowledgeable/smarter than you/right/...]. Anyone who would disagree is clearly [an idiot/partisan/lazy/...], and I fully expect to see them come out in droves now".
This risible style does far more to lower the tone than any linked article I've ever seen here.
