What brain-dead form of utilitarianism is that supposed to be? The "I'm-16-and-on-a-wikipedia-bender"-kind?
We don't hold 6-year-old children accountable for very much in a legal sense, because they are essentially animals able to (barely) speak. Thats why we instead regulate gun-ownership, so that no child has access to firearms. And if that doesn't seem to do the trick yet, I'd suggest regulating more comprehensively and holding parents accountable, so that it is very much in their own interest to keep guns from kids. We might also fund social services and schools to the extent that children are able to adequatley learn how to control their emotions and verbalise anger, unhapiness in a non-ciolent way, even if their parents are a bunch of irresponsible idiots.
That seem much preferable to executing a six year old every once in a while to be save.
Thanks Margot, for taking some time out of your busy schedule to post this fabulously intricate meta-contribution on bots, identity, and social media! Its much appreciated.
