Banning smoking in public places is an important issue on so many fronts, including health, that I think it should happen anyway

And little by little by little the rest of our freedom of choice is removed... what will you support them stopping next? Alcohol consumption (it is bad for you in the quantities normally imbibed by people going to pubs)? Fatty food consumption (it's for your own good you know)? Where does this nanny state end?
