There's a lot of decent and well-reasoned arguments against private gun ownership, but this is very far from one of them. In DC v. Heller, the Supreme Court held that the "well regulated militia" is a prefatory clause, and does not restrict gun ownership to militia related purposes. Additionally, the US Code defines the "militia" as all able-bodied male Americans over 18 years old, and all women in the National Guard, so this argument again fails, because we are by definition in the militia.

And don't give me the bullshit, somehow the comma's make the sentences have nothing to do with each other.

What you're saying is "don't tell me all the reasons why I'm wrong". There is an absolute wealth of secondary sources by the Founding Fathers about how private firearm ownership is so important, and how America is so unique in allowing its population to be armed. It's simply a lie to try to pretend that the Second Amendment confers anything less than an individual right to keep and bear arms.
