No shit people too stupid to own guns shouldn't own them, the question is that should the rights of many be sacrificed for the sins of a few? Both pragmatically and philosophically, the answer is no. I mean, if you believe in democracy, and you can recognize the contradiction between most of the voting population being mouthbreathers and still being determinant to how we make our decisions, you should be able to follow my argument. I want every right afforded to me to own weapons, because me not owning them doesn't have impact on the capacity of lawbreakers to own them, or on the competence of the police who I must rely on to protect me. Fuck cops and criminals
Instead you've devolve to appealing to emotion about the blood of children. *Rolls eyes*.
Yes, it's terrible, but thankfully, the amount of children who die in mass shootings annually is comparable with the amount of children who die from lightning strikes and slipping and falling in the bathroom.
That doesn't mean we shouldn't seek to mitigate it, but it does mean we should treat such incidences the way society handles everything else it can't guarantee against - proportional consequence for the perpetrator. No amount of gun control is going to stop a motivated actor as long as the laws of physics and chemistry exist. Forget an AR-15, you can kill almost 100 people driving a truck into a crowded population.
The world is a terrible place with an endless capacity for death and destruction. It's because of this that every man should place the responsibility upon themselves to be capable in some capacity to protect themselves and their family, and it's frankly embarrassing to abdicate yourself of that willingly, and hope and pray nothing bad will happen because you're European or whatever.
