I posted your sentence in it's entirety and and then posted "even if", to show how faulty your argument is. You have NO evidence that the bloger is a GOIG employee and you are incorrect about his name not being in evidence on the web page.
Even if you substitute 'all' in place of 'most' you are confronted with the obvious weakness/error in your conclusion.
I'm not addressing the author of the "article," but the original poster with the link and the subsequent questions from other posters.
That's your error. If you'd bothered to read the piece at the site you'd have seen that it is opinion and not news.
He can change his blog entries as much as he likes, and that still won't prove that he's a GOIG 'agent'.
