With all due respect, I have to disagree with your position on smoking ban(especially in bars). Why should the bar re-evaluate their value? Why shouldn't the individual contemplating on going to certain bar evaluate their value? If bar is smoking allowed, then the individual has to decide whether to go to that bar. He/She certainly has the choice.
Same as you, I am also a law abiding/tax-paying Candian citizen, and one that happens to light up a cigarette from time to time. You may not be aware, but price of the cigarette in Canada are approaching or exceeding $10. Greater than 50% of that is the tax imposed on my filthy habit, because the state deems it is the cost of the damage to the society incurred by smoking. I am definately fine with that. In purely economical stand point, if my habit caused society certain problems, I am willing to pay to fix it through tax on the cigarette.
I understand that most of you do not smoke, and has negative view of it and I agree. However, the choice should be in the hands of people who decides to smoke as long as they are responsible. As is common in any group of people(be it a group of NSXers or smokers), most of us are responsible in what we choose to do and only few of us are so-called "bad apples." Case in point, I smoke on my way to work in the morning. In my walk few blocks to the company building I try my best in staying out of people's way, respecting your right to not inhale the fume. I put it out and throw it in the garbage can near the building so it wouldn't look messy near the entrance. Should I NOT be allowed to smoke even if I do not cause any harm to the others?
If not, then why should some of you turn blind eye in people who decides to forego installing or by-passing catalyst in the exhaust? IT certainly has environmental effect as your exhaust is literally exuming toxic gas in to the air and further causes what some people would regard as noise polution(I am not picking on people who decides to let their NSX's beautiful exhaust roar and breath freely, this is just an example.)
What about the cost to the society due to obesity? It certainly costs Canadians billions of dollars every year(or so newspapers say) in health care, and obese people are NOT paying obesity TAX to cover the cost, are they? In that case, then, Chocolate should be banned, fast-foot should be banned and all the food that has more than 1% fat should be banned, shouldn't they? Further, let's imagine an extreme situation where yourself or your significant other is 8 month pregnant and need go somewhere on public transit, and all the 2 person benches are taken by obese people who takes both space so you/your SO can not find a seat. Then is this considered harmful or costly to the society? I would certainly consider it harmful to the health of my SO. So then obese people should be banned.(I'm not saying they should be. I respect their choice in lifestyle as long as they don't cause my family direct harm.)
So then, What the hell should we as a society do?
I think a little understand and respect for other people's choice would go a long way, in my humble opinion.
