Oh for godssakes, Rick, quit being such a drama queen. The actual military and economic defense of this country dwarfs the prospect of a couple of gays getting married. Get to the eminent business of the people and stop fussing over this non-issue. If worse comes to worse, let the states make up their own minds.
And, more importantly, knock off the boy-who-cried-wolf invocation of "Homeland Security"[tm] for sideshow non-issues. It degrades the effectiveness of actual homeland security warnings (and thus just might tip the balance between getting thousands of us killed, or not).
