You can deflect and change the exact point of discussion all you want, it doesn't alter the fact that this will do little to reduce mass shootings and is largely hot air.
It will be interesting to see how many rifles capable of doing the exact same damage, but without the scary black metal body, remain available to would be mass shooters after the ban has taken place. I imagine there will be plenty, unless they are banning all semi-automatic rifles, leaving only bolt action.
