The more fundamental human right is the right to not be blasted by an angry teenager who's been reading crazy things on the internet. In the hierarchy of human rights, that once has precedence.
Do you see the problem with that sort of thinking?
You haven't even represented the true content of the 2nd amendment so there's nothing to talk about here. The 2nd amendment is about militias, not "give everyone and their toddler access to massive fire power at all times".
"A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed."
Tell me where that says guns should be available to deranged person who wants one. Everyone should get a hand gun, a rifle, and a shotgun, and make it double.
