Agreed, that is the problem with ‘cookie-cutter’ categories for denying 2A rights.
Felons can’t own? We’ll make ALL crime a felony, and also, broaden the categories of ‘crime’.
Mentally deficient can’t own, well we can broaden that definition too.
No-Fly-List can’t own, whoa, this is getting easier.
I have a friend who ran away with his girlfriend. He was 18 or so and she was around 16. He was charged with kidnapping and can never own a gun for the rest of his life. He’s cleaned up and is a very good, godly man. He can’t protect his family.
