“The only thing necessary for the triumph of evil is for good men to do nothing.” That quote is in of its essence a path to the solution of evil. The quote is of dubious origins but a foundation for many great acts, including many of Teddy Roosevelts efforts at social and environmental change, protection, and growth.
Preventing one act of evil is a solution to that evil. So yes, the extra people killed by things that didn't have to be, they mattered. The families of Sandy Hook children killed empathize differently with those kill after the 10th victim. All hate of course what happened. The magic number is not hard for many to understand, it is every one that something could have been done something about. There will always be a line where this is blurry and, to your point, in some reducing to the absurd sense, that could sort have theoretically been all. But see that's where all of here agree, its not all. But its also not none, that where you perspective cannot prevail and will not prevail here. A total gun ban is actually not logical in the actual world, we agree that would be illogical.
And you know, I really am sorry to hear that you think others influence cannot matter. Because there's really only one way a person ultimately gets to that point, which is that they deeply and truly believe their influence has not mattered. But then they also tend to desperately be heard. We are hearing you, we are responding to you. Some agree with you. Some do not. I hope you can believe though, that your influence could be good and matter. I believe that would change, less importantly, how you are coming at this, and more importantly, how you come at other things in your life.
Dang I sound like such a goofball even to myself, but I can't help myself either
