Re: Alcohol vs smoking (PM Mailbag Friday, 23 May 2014) On the contrary. I’m very much a Libertarian. My reply was meant to show the irony of the original message. As far as I’m concerned, I subscribe to Heinlein’s definition of sin “the only sin is hurting someone else unnecessarily”. If you’re not hurting someone else, you should be able to do what you want. You want to smoke? Go for it. You want to smoke *in public*? Now you’re hurting someone else.
