because that is a separate clause, meant in this case to give an example of how the individual right protected in the amendment could be exercised.

"The second amendment protects an individual's right to possess a firearm, unconnected with service in a militia, for traditionally lawful purposes."

If you still aren't sure what the original intentions of this amendment were then here are a few quotes from founding fathers, particularly those who were supportive of a bill of rights at the time:

"To disarm the people ... is the most effectual way to enslave them."

-George Mason

“Guard with jealous attention the public liberty. Suspect everyone who approaches that jewel. Unfortunately, nothing will preserve it but downright force. Whenever you give up that force, you are ruined…. The great object is that every man be armed. Everyone who is able might have a gun.” – Patrick Henry, Speech to the Virginia Ratifying Convention, June 5, 1778

“The Constitution of most of our states (and of the United States) assert that all power is inherent in the people; that they may exercise it by themselves; that it is their right and duty to be at all times armed.” – Thomas Jefferson, letter to to John Cartwright, 5 June 1824

“The Constitution shall never be construed to prevent the people of the United States who are peaceable citizens from keeping their own arms.” – Samuel Adams, Massachusetts Ratifying Convention, January 9–February 5, 1788

“The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes…. Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man.” – Thomas Jefferson, Commonplace Book (quoting 18th century criminologist Cesare Beccaria), 1774-1776

“I ask who are the militia? They consist now of the whole people, except a few public officers.” – George Mason, address to the Virginia Ratifying Convention, June 4, 1788

>And you? Are you going to sign up? Or are you going to fight the fight from behind your keyboard

I mean, you are the one calling for the federal government to do the dirty work and lock down on peoples freedoms nationwide. Can't be less self aware than that

>There are plenty of "arms" citizens are not allowed to buy.

and that itself is a violation of the 2nd amendment and our natural rights.

"Shall not be infringed" cannot be much clearer but there are still millions of people who think there is room for restriction

banning the sale of guns entirely is something that, for one, almost every state and local government in the country would refuse to enforce. Two, would cause riots around the country. And three, the federal government doesn't even have the power to do that. It was designed that way from the very beginning
