Let’s see if I can come up with something that will offend as many people as possible. . . ..
AS it can be shown that most “mass” shootings are connected with some form of mental disturbance or illness. . . .
AND it can be shown that many, many forms of mental illness/disturbance are connected to Libtardism (“progressivism”) and/or religious fanaticism. (I leave it as an exercise for the readers to show the chain between Libtardism and religious fanaticism, with The State being the Libtard’s religion of choice).
SINCE State Religion Libtardism, and Islam jihadism seem to be the primary culprits in these current spate of mass shootings,
THEN restrict the purchasing of guns from Libtards and muzzies.
TO MAKE a list of either/both:
IF you have voted DemonRat in both of the last two FedGov elections (i.e., O’Bozo), THEN you’re a Libtard, and will NOT be allowed to buy guns.
IF you attend mosque on even a semi-regular basis, THEN you’re a muzzie, and THEREFORE a potential jihadist, and will NOT be allowed to buy guns.

And once you’re on the Restricted List, good luck getting yourself off of it. (I figure what’s sauce for the goose, is sauce for the gander. And if the DemonRats want to get THEIR Favorite Children off the Restricted List, then they will fix that system, so that the innocent will also be able to get themselves off the List).
