Line 5 and 6 seem to contradict each other. From 5 it looks like you want to more "gun licensing" and in line 6 you want not to "deny rights". Whereas gun licensing (any licensing, technically speaking) is the denial of right. And any argument (of which there are many valid ones) for gun licensing is precisely what you're arguing against: "Everyone gotta have The Gun License because think of the children" ... even if it deprives someone from the right to protect their life.
