Him: “Civilians shouldn’t have AR-15s!”
Me: Didn’t serve, or oath-breaker?
Him: “I was a tank commander!”
Me: All you had to say was “oath-breaker”.
Him: “I am an American.”
Me: Did you magically become a tank commander without swearing an oath to defend the Constitution? Or did your oath come with an expiration date? If the answer to neither of those is “no”, then you are an oath-breaker. The accident of your place of birth means nothing to me.
