You obviously don't because you're interpreting it wrong.

Constitutional scholars interpret "A well-regulated militia being necessary for the security of a free state" as a prefatory clause, with "The right of the people to keep and bear arms shall not be infringed" as the operating clause. The first is there to explain why the second is there, not to limit its scope.

You know the first time this whole militia crap came up? Dred Scott v. Sandford, 1856. "But if we give negroes citizenship, that means they'll be allowed to have guns!" Which minority group do you personally want it to be safer for white men to systematically brutalize? Black people? Women? Gay people? Trans people? Jews? Muslims?
