typically I haven't much cared one way or another.  That so long as you respect my right to not own a gun it doesn't particularly matter to me if you keep weapons.   Sure, every now and then (and more and more often anymore) when some unwell individual goes off it causes me to think.  But mostly the issue of guns hasn't been high on my list of concerns.  
It is getting there.  I think what might have done recently it is watching a man being interviewed on the news this past week.  A father.  Doing his best to speak coherently about his little girl.   His little angel.  Who had recently been shredded while at school in Florida.  Literally cut in half.  And right after that interview was discussion with the head of the NRA, made a millionaire by members dues, blindly raging how, through his convenient interpretation, the Second Amendment of the Constitution give people the right to have the weapons used to dismember children.  

I think I may be starting to care.  All I can figure is its part of getting old because it's happening to me more and more lately.  
That the Second Amendment continues to be misinterpreted to the benefit of those in favor of gun ownership remains one of the biggest stains on our nation. The language of the second amendment is clear, and, to me so is the intent. The Second Amendment provides for armed militias for purpose of protection of the state.  Put another way - as a group we can own weapons to be used for protection of the government.  

No reasonable interpretation allows me to have my very own goddamn machine gun, whether I use it for "hunting" or mowing down school children.  In fact, the Second Amendment doesn't guarantee me the right to own even a water pistol.  Instead, it explicitly allows the government to decide who can bear arms, and when.  It provides for, even requires government regulation of firearms.  

Or, as put by Supreme Court Chief Justice Warren Burger:  "The Gun Lobby's interpretation of the Second Amendment is one of the greatest pieces of fraud - I repeat the word fraud - on the American people by special interest groups that I have ever seen in my lifetime.   The actual purpose of the Second Amendment was to ensure that State armies - the militia - would be maintained for the defense of the State.  The very language of the Second Amendment refutes the argument that it was intended to guarantee every citizen an unfettered right to any weapon."  

For those of you who don't remember Justice Burger - he was considered conservative, very.  He'd have made Stevie Bannon look like a daffodil-toting liberal. Basically he was a redneck's dream. 

Well, except for his annoying tendency to state the truth.  In this case, that you, me neither of us has a constitutional right to own a weapon whether it be firearm or butter knife.

The Second Amendment is clear.   Misinterpretation to the benefit of private gun owners requires massive sums of money and political clout.  Enter the NRA and gun manufacturers, e.g. very wealthy individuals and groups, , padding politicians pockets lest they might actually start enforcing the guiding documents of the United States of America.  Rather than using their positions of power to be part of the solution, rather than seizing on a true opportunity to make things better - they instead continue with their hate-filled rhetoric, pushing self serving and blatantly incorrect legal arguments to the massive benefits of their wallets.    

And in so doing absolutely positively 100% guaranteeing more massacres. 

We all know that.  The only real question is how do we continue rationalizing our part in putting 11 bullets into a nine-year girl whos biggest sin was going to school on an unlucky day.
