And, 200 years ago, social media was a printing press.  Yet here you are exercising your First Amendment Rights by displaying a total lack of knowledge of relevant history on the Internet.  Changes in technology do not affect basic rights.

The Second Amendment came from English Common law.  It is presumed that you have the "God given" right to defend yourself - especially in your home.  In addition, the founders of the Bill of Rights wrote that your basic right to defend yourself extends to the right to defend yourself from a Tyrannical Government.

It has nothing to do with our "unmatched professional military".  In fact, it was an "unmatched professional military" of the Federal Government that they were worried about.  They wanted to give the common man both the responsibility and the right to bear small arms.  And militia membership was not required.

In fact, it was the "unmatched professional military" in Nazi Germany that took advantage of the Jews who had been disarmed.
