Well, when I first posted the top comment was inaccurately claiming that the speed of light in the article is wrong. The other top comment was a one sentence dismissal that clearly didn't even read the article, and it has since been removed for this reason.

So yes, I do think my initial assessment was accurate. And no, your comment isn't helpful, simply pointing out an overly dismissive comment is, in fact, overly dismissive, is not in itself being overly dismissive. Some people simply don't want to contribute meaningfully to the discussion, or are flat out dishonest, and there's nothing dismissive about pointing that out.
