Why don't I ever hear Conservatives spouting off about "the definition of war" like they do with marriage?

Well, the president has the power to move troops for a period of time before congress can declare war or force him to withdraw... they did nothing which might as well have been declaring war. But all this is a mute point, considering it is all contained within the governemnt. With marriage, it is the definition of the state vs the definition of religious institutions. The government cannot infringe upon the rights of religion... hence the government cannot legalize gay marriage, as it would infringe on these rights... not parallel examples, deary.
