Would you tell them "Sorry but this is inhumane, I can't let you do that to yourself and I'm ready to vote laws to forbid you to do as you please with your free time and send people like you to jail if they persist"? Do you know better than they do what's best for them and how they can use their own body? Doesn't that make you an authoritarian?
