Smoke-free workplaces help prevent people from dying of cancer just to make a living.
Yep, this be incorrect nonsense.
I'd provide (plenty of) links to back up my position but a google search on: secondhand smoke debunked would likely pull up the ones I would readily use.
Which even for a moment, let's just consider the idea that SHS is possibly harmful, then you come to the SHV (secondhand vapor) arguments which are using THE EXACT SAME logic to try to persuade people. But not only is there negligible amounts of harm associated with it, akin to exhaled human breath, it is arguably better for you than exhaled human breath. Yet, is treated as equal to SHS (from the position that hasn't investigated the debunking, or perhaps has but is willing to lie).
If people honestly, truly believe something like SHV can cause them grave harm then in our reality everyone ought to be wearing filters over their mouth for there is evidence that human breath contains harmful chemicals. Deadly in fact. Just pay no attention to the fact that it is in such minute amounts to be (forever equal to) negligible harm. But propagandists don't bring this up and instead just cite data that "SHV contains deadly chemicals."
I find it helpful, honestly, that SHS harms have been debunked.
I also do think there is a direct relation between anti-smoking rhetoric (heavily promoted at one point by German Nazis, arguably the birthplace of such rhetoric) and American' PC'ism. Hard to make a real quick, solid case for this, but I really do think that the empowerment that anti-smoking types have gotten from their 'successful' battling has been seen as way to tackle other avenues/issues that people wish to change the narrative on.
There is actually a 'game plan' from anti-smoking advocates that has been leaked (akin to WikiLeaks) that shows it was always intended as a propaganda tool, not a public health issue. This game plan dates back to early 1960's. Now that they are doing the same thing with vaping, I see them (anti-types) as overplaying their hand. I was one that at one point was borderline anti-smoking, because of the propaganda (never really researched it). But because they chose to overplay their hand in what struck me as "this doesn't make sense what they are now purporting with regards to vapor," I've seen that they were intentionally lying all along, and literally creating a narrative for "political correctness." I see it as no different than how prohibitionists in 1920's must have tried to persuade people into their version of righteousness. That, obviously, failed. The anti-smoking one is still with us, but if I had a dollar for every person I've come across that is so under-prepared for reasonable debate on this topic, I'd have enough money to make sure a third party candidate could compete in this year's U.S. elections for POTUS.
