My Opinion as I don't know the OP is that just because it is not illegal or against the rules doesn't mean it is "proper". I have a issues with smoking in public, my 10 year old typically comes along to shows with me and I am appalled at just how rude "some" smokers are. They stand as close to the door as they can puffing away, inhale and run through the door so they can exhale inside the building. Why do I and my child have to inhale your poisons? Why does my son, have to hold his breath to walk past people? I get the entire your rights / my right deal...and therefore we just deal and hold our breath but personally I find it "not proper". Then you add "vaping" and smokers somehow believe it is safer (still has the poisons) and they can then do it anywhere. Your right its not illegal or against the rules (hopefully this will change) but I guarantee you will never get any of my business when you expose me and mine to health risks. What you do personally is up to you but why must I be impacted by it unwillingly? (we all have to share this planet and sometimes common curtsy needs to rule even if not illegal)
Again not targeting the OP just trying to give some context behind why he might have said it was "not proper".
Let the flaming commence.
Well, maybe I don't like your haircut, might influence my children (great grandchildren) to cut theirs the same way (really infuriates me). Maybe I don't like the way you dress, or play with your damn phone, interfering with my communications.
YOU nor I have the right to interfere with others lives. If you really look at second hand cigarette smoke effects when outside (probably inside is way overblown) the effects are far less than the effects from the fumes from firearm "smoke", cleaning solutions used inside, even smoke from frying inside. Your aversion to smoking is noted - in my case ignored. By the way I am 72 years old, father smoked while I was raised, and I have smoked for over 50 years, still with clear lungs, no cancer or other health effect my doctor can detect. LIFE is not safe, I am sure something will kill me in the next few years, as far as I know the current death rate per 1,000 is 100% over a century or so.
