War Supporters and War Opponents

War supporters are sometimes criticized for not actually sacrificing anything themselves for the war effort. It's a variation on the chickenhawk argument - that war support is somehow disengenuous unless it is backed up with appropriate action (ie serving yourself, you pussy!)

But why aren't war opponents held to the same standard? If war opponents are sooooo opposed to the war, why aren't they doing anything to stop it?

Just a thought.
