Obligatory Universal Background Checks are not about preventing any one particularly dangerous individual from obtaining a gun, they are about creating general conditions that will make it more costly, time consuming for the general population to arm itself... with the aim of reducing, over time, the prevalence of gun ownership amongst those that are inclined to follow the law, i.e. taxpayers. More alarmingly such laws will slowly but surely condition people to accept the false premise that they must get "permission" from the State to own a weapon.
You do not need "permission" to exercise the Right to Keep and Bear Arms any more than you would need it to breathe.
