It's grossly misrepresenting the response to the memo to imply it was just a matter of challenging and questioning. A quick read of any of the forums where it's being discussed makes that clear, and remember how the author was fired?

A lot of the issue people have with the response is precisely that it wasn't making a substantive attempt to actually question or challenge the memo's content.
