I appreciate that you read them and have your personal view of what they say. I too have a reading of both of them (which is probably not that far from yours - as said before, I am pro Heller and big on freedom of speech and religion). I also know a bunch of folks who read them differently. They are just as able and earnest as you and I. So, who is to say which of the 2-4 readings of the 2A and countless readings of the 1A are right?
If we are to be a “nation of laws, not men” (a basic principle of many Founders) we have to find a way to have one binding answer, we can’t all have our own. There is no way to run a lawful society if every citizen retains the personal and absolute right to live by their own personal definitions of the constitution or statutes.
For the last 217 years the answer for when folks disagree is that the final answer is provided by the Supreme Court (and in many cases they disagree within themselves). So, if you are committed to the rule of law then Supreme Court jurisprudence is required to understand the meets and bounds of our constitutional rights. It has proven an imperfect system, but still the best humanity has been able to come up with so far in my opinion.
