To be taken seriously on any subject, a writer first must learn to write. This author has a very long way to go.
If you look closer, you'll realize that the guy is quite intelligent and very well informed, but he's just not a native English speaker. I can't, of course, infer what his original language is, or was, but he's definitely using English as a second language and not doing a half-bad job of it either.
Take care...
