Whilst we blame the NRA and manufacturers for nailing and bracing the key log in place, we don’t blame all the other logs, but we do question them for allowing it to happen.
My point is your extremist argument isn’t valid, because whilst one side is taking the extreme position of letting anyone own a gun, even those incapable of being responsible, the rest of us aren’t demanding an absolute ban, which is the other extreme; we’re merely suggesting checks on the responsibility of potential owners and limiting children’s access to them, that seems to be a very reasonable position (far from extreme).
