There are plenty of other comments from other non hub users on this site regarding his article. I joined so that I could find somewhere to post within hub pages. I suspect that my opinions (which are backed by sources) point out some fundamental flaws in the authors argument. The fact that the author is being selective about which comments are allowed to be posted is ridiculous.
If the author didn't want outside comments on his article, then why is it a public page with the option to comment?
Updated: I posted yesterday on his article as "Steven" supporting his article. It was approved by the author. He is simply removing posts that don't align with what he believes. Amazing.
