Liberals should support the war

I was reading an interesting article about why liberals should support the war in Iraq. It was written from a liberal who believes in socially liberal causes such as gay marriage. His argument was that the very people who are against the war on terrorism are also the ones who most passionately disagree with the ideology of Islamic nations (i.e. Sharia law which opposes gays, women and a whole host of "liberal" causes). I'm not sure that his argument is a great parallel, but it is an interesting observation.
