Most leftists don't think all guns are always bad so I'm not sure what value they're supposedly turning on here. Pretty sure the prevailing complaint on the left is about how easy it is to acquire a firearm, not that people have them.
I support people's right to own weapons but it should be a lot harder to purchase and there should be MUCH greater punishments if the weapon you own is used in a shooting (I'm thinking parents of school shooters who poorly secured their guns)
