I don’t argue from a public health standpoint. I argue from a nuisance standpoint.
For example, there are noise, urination and defecation ordinances for public spaces (among others). Likewise, a smoking ordinance would make sense on the same basis.
On private property, property owners should set their own policies.
It seems you are actually admitting secondary tobacco smoke is not a real public health hazard.
I particularly dislike willfully stupid people.
Can we also ban them from public places?
