What is that?

"MHO Professor As'ad AbuKhalil’s blog http://angryarab.blogspot.com/ would be OK for personal opinion on topics he’s an expert on. However, quoting at length from this short personal attack that provides no evidence for the insult hurled really does go against WP:RS for BLP. I am even wondering if any mention of his blog post belongs in the article at all. (And yes it’s Gilad Atzmon again.) Thoughts?"
