Who ever wrote that article was an idiot. Do you have a link?

So you are condemning an unknown author based on a work you haven't read?  You have it backwards.  You ask for a link first.  In my short time here I've learned never to trust an OP.  Read the article first.  It is often either completely different from the OP or at a minimum much more nuanced.
