Appealing to the safety of children is what Republicans do to trick voters to join them. You are attempting to do the same here and have a inauthentic argument; unless you have a plan to guarantee to get rid of all weapons, people are going to kill other people including kids. I don't know if you are aware of this, but criminals and insane people don't follow the laws and will still stay armed.
And thinking an armed populace is any kind of threat to a modern military? That’s ridiculous.
