This overused retort by conservatives and the military-obsessed always bothered me. These are the same people who say we'd all be "speaking German" right now if liberals had their way (giving Hitler's Germany an incredible benefit of the doubt in waging a successful Trans-Atlantic invasion of the North American Continent). The truth is, after the Revolutionary War, most rights weren't fought for in Wars. Sorry.
People did die in battle for our rights, but most of them were in the streets of America and Colorado Mining towns.
