I'm in favor of the second amendment as it's written, not as it's interpreted; I also believe that there should be strict legislation regarding licensing for ownership. One should be able to pass a basic competency test and take a course on gun safety before owning a gun, much the same as owning a car
That said, the one that's more important to me is the First Amendment; if you can't criticize the ruling class and run in opposition of them politically, then the second amendment means nothing
I mean, the second amendment is the one to protect the constitution, and the rest are to protect the rights of the people. And you do realize that if we had a totalitarian government that was tyrannical, what would those competency tests look like? Do you really think the majority of people would pass if the government wanted to seize control of everyone? Giving that much power to the government is like saying "Here's my only means of defence against you. You can have it, friend"
