I cannot argue with your logic, and I would say that you accomplished something important - to make us think. Logic and common sense seems ever more...uncommon. This seems particularly true when it comes to the second amendment, especially now. Emotions are running so high, as they should. But, "The one who does not violate the life, liberty, or property of others does not owe you any explanation, excuse, or apology". I am tired so tired of others trying to make me feel like I have done something wrong, or that I am somehow responsible for the events of the day. In fact, I have not, am not. Thank you for pointing that out.
The urge to find a scapegoat is strong. The urge to use politics to punish the scapegoat is stronger. We need to constantly present the philosophy of liberty instead.
