I'd take most blogs of any political persuasion over a Newsweek opinion piece.

It seems like you're not even giving the arguments any thought. If you don't think he checks his facts, then find what's incorrect. If his arguments are false, then refute them.

But don't entirely dismiss them because you don't agree with them. The validity of an argument is not determined by whether or not it's written in Newsweek.
