Since this is your interpretation of the Second Amendment, please give us your interpretation of the First Amendment and the entire Constitution.
It's only as good as the men who are charged with enforcing it. With precious few notable exceptions (maybe only 1?), the ones we have today have great regard for their own reelection -- under the guise of "doing the will of the people" (sometimes the people are WRONG!) -- and little if any regard for their Constitutional duties.
To wit: How many Supreme Court justices have been impeached over the past 50 years? How much more will the SCOTUS be allowed to twist and dilute the First and Second Amendments before the House says, "Enough already, you're outta here!"?
