The level of ignorance of people dissing the article without reading it is not astonishing, it's par for the course.
I feel that's an unwarranted assumption on your part: I read the article, even quoted from it in my comment, and my take agrees with your parent comments.
Your comment smells a lot like "They disagree with the article, so obviously they didn't read it, because anyone who read it would agree".
I won't respond further.
The "extraordinary claim" is obviously that a SciAm article is "stupid" and that "The emperor is naked, we can all see it".
