A fight against the right of Americans to own guns is one that almost certainly can never be won. But a concerted effort to make gun ownership safer by enacting and strengthening common sense efforts to protect public safety through, for example, closing the gun show loophole and banning bullet clips that hold 100 shells, can and must be won if we want to reduce gun violence in the US. And the way to win that fight is to paint the NRA, which takes advantage of its own members in order to promote a reactionary and dangerous agenda of turning the US into a version of the old Wild West, as the out-of-control villain that it is.
It might be all from the same source but I have seen several instances where the anti-gun people are advocating restrictions on 100 round magazines with no mention of a 10 round limit as is the usual threshold for demonic possession.
While that is certain to ease the political resistance to capacity restrictions on firearms the statistics where such magazines played a definitive role in the execution of a crime are going to be exceedingly poor. I would be willing to bet that you will find a much higher correlation to crimes committed by people wearing gray hoodies greater than size XL simultaneously with size 12 or greater Nike shoes than you would to 100 round magazines being correlated to crime.
But don’t expect the facts and logic to be important to these people. It’s about the implicitly admitted long term fight “against the right of Americans to own guns.” The 100 round threshold is the camel’s nose.
