I want to hone in on this particular statement you made for some clarification. Are you referring to violence here? If the state or law enforcement are involved, what's the response?
Just trying to get an idea of what "defend that right" is supposed to mean here, since I hear it an awful lot in regards to this specific topic.
Just because something is the law it doesn't mean it's a sensible law nor that law should never be changed to reflect modern cultures. Otherwise you'd still be going round drowning women in rivers to prove they're innocence of witch crimes.
There has been so much evidence to prove that America's lack of gun control is counter productive:
* higher suicide rates
* the numbers family members accidentally killed by their own guns
* mass shootings
Even when looking at the figures in isolation, it's pretty damning. Then when you compare to statistics in the rest of the world, America's statistics become nothing short of embarrassing.
What's more, the UK, Australia and some other countries went through the same process of having relaxed gun control laws and then tightening them up because they came to the same realisation that guns are not comparable to free speech, power tools, nor any other the other dumb things pro-gun lobbies compare them with.
