If anyone gave their life SPEFICIFALLY to save their right to bear arms, then I call them morons who wasted their life on an outdated ideal. If you're talking about service members that gave their lives in defence of our nation, then I say they were defending the constitution and the American way of life, not specifically gun rights.
Saying that any part of the constitution is more important than the lives of the people it was written to protect is outright and willfull ignorance. Most likely spoken by a scared person who believes a few guns will save him from a tyrannical government that wields the most effective military in history.
Once people like you realize that it's your voice, not your guns, that is you most effective weapon the nation will be much better off.
