Some things are not curable. Even if you show your friend the kind of information you are seeking, it won't matter. The justification for the action might change, but trust me, it will continue.
You are right. I post the links hoping a lurker can use them. But once someone hates a smoker, it will never change. Never ever. Plus, it gives them someone to pound on. I wonder who they would trash and bash if it wasn't for a smoker?
