C'mon. Just look at this article's characterization of Al Jazeera, hardly impartial. Please tell me you're not that naive and that you can distinguish fact from opinion.
This statement doesn't amount to much at all if that the characterization of Al Jazeera is correct. Can you present an argument that it's actually wrong, or do you want to take that as a given?
More generally, though, I've found Taheri to be extremely knowlegeable about the middle east. His columns are quite frequently informative, and his arguments often insightful. Don't like his characterization of Al Jazeera? Fine, but I bet he watches a lot more than either of us, and he doesn't need to rely on someone else for translations either, as so many western commentators do. In the absence of a counterargument to his characterization, I'm actually quite willing to accept his word.
And the heart of his argument isn't even about Al Jazeera, but about the role of political groups, and the Syrian regime in particular, of stoking this fire, and how the riots represent the result of those efforts rather than any spontaneous muslim rage. And details such as the delay between publication and response, the fake "cartoons" added to the list, the burning of embassies in Syria and Lebanon, point pretty convincingly towards that conclusion. If you've got a better way to explain those facts based on
"the buildup of public discontent for what they perceive to be attacks on Muslims," then by all means, present the argument.
