2nd Amendment, Bill Of Rights, Constitution, Where are we headed?

  As I sit on FaceBook and read the uneducated comments and backlash from the right to the left, from the left to the right, I do not engage. If I want to talk politics I will do so with someone slightly  educated on the subject whether they agree with me or not.
  In our concealed handgun classes we preach (teach) "Read, Study, Learn". Do that. We have all been told history is doomed to repeat itself. And, history has proved that.
  Read, study, learn.
  There was a reason for the second amendment. There are those who say it is outdated. Those are wrong.
 Why was it worded the way that it was?
 Why did our founding fathers think it was necessary to protect these rights?
 Can it happen to us again?
Read the constitution. What led to the Declaration of Independence? Why did some of our forefathers refuse to roll over to the tyranny of our government?

There are several versions of the text of the Second Amendment, each with slight capitalization and punctuation differences, found in the official documents surrounding the adoption of the Bill of Rights.^[5] One version was passed by the Congress,^[6] while another is found in the copies distributed to the States^[7] and then ratified by them.

As passed by the Congress:

A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.

As ratified by the States and authenticated by Thomas Jefferson, Secretary of State:

A well regulated militia being necessary to the security of a free state, the right of the people to keep and bear arms shall not be infringed.^[8]

I have seen nothing in recent history that negates the need for our protection and freedom.
