Let's not get hysterical - "supporting death"  - c'mon ...
Not wanting to ban bump stocks is merely pandering to those who love going to places like old quarries and blasting off a few hundred or a thousand rounds as a way of getting their kicks.  And there's a lot more of those folks than there are mass murderers.

There's no home or personal defense rational, no hunting rational - just wanting to protect a very small subset of gun owners so they can have their fun.  This will and should 'backfire' on the NRA - without the hysterics.
