Yet, even though smoking rates have declined in the West, the fact there are still 10million puffers suggests smoking remains a pretty normal activity.
I have no way of knowing if that 10 million figure is accurate, but that is actually a rather small minority. Not nearly enough to label something a "normal activity" IMO. Especially if that is 10 million "in the West", meaning all Western countries as stated. One thing's for sure, there are FAR less tobacco users now than there were in past decades.
As for the alienation, I would simply pose the same question I always do to non-tobacco users: Why is there an ever-increasing epidemic of cancer of all types among non-tobacco users, including and especially in children?
I would also say this regarding the alienation: It is, imo, primarily a programmed, Pavlovian response people have...the result of propaganda...the "2nd and 3rd hand smoke" bullshit. If they were propagandized in the same relentless manner about any number of other things they are exposed to and ingest on a daily basis they'd suddenly respond the same way to those things.
Instead when they or their children are diagnosed with cancer they will simply accept without question that it's not possible to know what caused it...because that's what the cancer industry wants them to believe...and they'll go on ingesting the same toxins every day that "normal" people always do, in their food, water and air.
It's a very common sight to see someone jogging down the sidewalk on a busy street engulfed in exhaust fumes, even though they could easily be jogging elsewhere away from the cars. These same people would probably freak out if they got a whiff of tobacco smoke.
