Except, in my specific argument stated, nobody is filling up anyone's lungs with evil second hand smoke (which, by the way, is just as foul, if less so, than a lot of other carcinogens that nobody cares about). If you want to go to a bar that allows smoking, that's your own risk. A person that runs a privately owned establishment shouldn't be forced to bend to what you want, especially in regards to a legal substance, albeit harmful.
