The people who compose the militia.
We've discussed this before, but I'll take the time to go over this again. I understand you're new, so it's excusable.
Let's look at some of the other Amendments to the US Constitution that use the words "The right of the people"
Amendment I
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the
right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
This mean ALL people, not just people who are approved.
Amendment IV
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated,
Again, the right of the people. All people. Everyone.
Amendment IX
The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by
the people.
Again, the people. Not just some. ALL.
Now, does the 1st, 6th, and 11th amendment apply to all people? Yes. The right of the people.
Hope this helps. Now, there's that pesky word militia you're referring to. You'll need to find out what they meant when they referred to a militia.
