From a purely aesthetic perspective, someone waving their arms, holding their nose, and talking loudly about how disgusting smokers are as they walk past a cigarette smoker is far more unpleasant than the original act. Theatrical public shaming is one of the ugliest things in society.

Given the strong association with SIDS and cigarette smoke the desire of parents to get their newborn babies away from the poison is not theatrical. It is practical.

I don’t know what to tell you, but there’s a fundamental difference between being the transgressor and responding to a transgression.

And I say this, FWIW, as a on and off smoker.

FWIW, I have never smoked a cigarette in my life. (But did grow up, as the child of anthropologist parents, frequently sitting near wood cook fires in small smoke-filled huts, which is at least 1000x worse than any second-hand cigarette smoke you could possibly get outside.)

There is a fundamental difference between someone minding their own business on a public street, not harming anyone else, and someone else putting on a show to shame them based on gross mis-assessment of risk.

I’m not sure what to say here. You have reiterated that there is no health issue, but my point is that whether or not a given behavior presents a physical harm to others is not the sole standard by which public behavior is governed.
