You're apparently operating from the premise that second-hand smoke is a killer. Sorry, you don't get to define the terms of the argument, painful as it must be to a narcissist such as yourself.
I love arguing with brick walls (and naive extreme libertarians).
Of course you don't love "arguing."
You require complete acquiescence to any assertion you make.
Do you buy your brown shirts off the rack, or are they tailored?
I'm not going to continue this dialogue if you don't acknowledge that secondhand smoke is harmful.
