On the death penalty: "Mere factual innocence is no reason not to carry out a death sentence properly reached."
In deciding that private businesses can be exempted from certain laws on religious grounds: “Well, religious beliefs aren’t reasonable. I mean, religious beliefs are categorical. You know, it’s God [that] tells you. It’s not a matter of being reasonable."
On the right of Americans to arm themselves with anything that can be hand-carried: "I suppose there are hand-held rocket launchers that can bring down airplanes, that will have to be decided.”

On his belief that racism no longer exists and that the Voting Rights Act is no longer needed: "[There is a] phenomenon that is called perpetuation of racial entitlement. It’s been written about.
