The best argument I've seen recently for banning this style of weapon comes from the corporations involved. I'm linking to a video where they show off some nonsense that actually clarified the other side's arguments: They're lying about what their weapons even are and how people should use them. See the video for this "Pistol Stabilizing Brace" where you see a guy firing what is obviously a small rifle in some sort of nonsense way to make it not illegal to call that thing a pistol.
I spent my whole life being told by conservatives that they don't want to think beyond "If it looks like a duck and quacks like a duck it must be a duck" and then they pretend this stupid shit looks fine to them.
It looks like that dumb scene in Once Upon a Time In Mexico where they gave Antonio Banderas fake guns and added all of the muzzle flash and bullets later. He's flopping around on his back with a rifle in each hand and they're just swinging around wildly while he pretends to fire them.
We come here in search of a place to express our thoughts outside of the direct control and surveillance of unaccountable, mega-corporations. There is no common theme that binds us other than these being the bonds we've chosen rather than those that have been chosen for us.
