Funny story: I was recently at a night club talking to some girl who unexpectedly began to tell me how much she hates smoking and how she wants it banned. I wasn't in the mood to get in a huge political debate (especially when the whole thing would have to be yelled over loud music). But I couldn't agree to health fascism. So I was stuck in the awkward position of not agreeing but not disagreeing. This can become pretty unintentionally funny after a few minutes.
Girl: So I like, hate smoking, and want it banned.
Me: That's...interesting. I never knew you were so into bans on things.
Girl: I think the people who complain about smoking bans are silly.
Me: Yeah--silly people. How about them? eh?
Girl: Smokers sicken me, and the law should stop them.
Me: Laws. How about them? eh?
Girl: I don't think smoking bans hurt businesses at all.
Me: I like businesses. Businesses are good, m'kay.
Looking back, maybe it would have been smarter to go the opposite route.
