Absolutely not. I'd go further and say we shouldn't let them drag science into the debate, but they always will. It's a civil liberties issue and I wish we could keep it on that plane.
Smoking bans are going to be as successful as the law that spawned speakeasies in the 1920's. Successful at diminishing respect for the law and whittling away at the concept of property rights and increasing the number of criminals.
Alice's Restaurant comes to mind. (Q: What are you in for, kid? A: I'm a litterbug.)
Waste of taxpayer loot, waste of law enforcement officers. Increased power to the nanny state.
Nevertheless, smoking is an unwholesome habit and we have bigger and more urgent battles. Like gun ownership. Governor Rendell is again trying to outlaw guns in Philadelphia.
Let's have that fight. At least we won't be diverted by totalitarians saying, you're an addict and you stink like a gun. ;)
I think it's a bit of a stretch to imply that anti-anti-smoking detracts from the campaign against gun control. There is only so much time in the day so I suppose you could have a minor point. But I would also think that the cigarette odor could also help mask the smell of gunpowder; if I were a smoker I'd be less nervous getting pulled over.
