But what you don't seem to get is that I was never really at odds with your opinion for the most part. But, you said comparing smoking to cars isn't valid, missed the point that was being made, and have been firing stupidity from the hip ever since.
Point being, that it seems only smokers (and the obese) are held to such standards, but people make unhealthy choices that are often not the most 'green' all the time. Choices that can and do have some negative effect on those around that person. Should we look down on people who BBQ? Should we look down on someone who owns a car that gets less than 40 mpg? Should we look down on those who would eat an unhealthy lunch at McD's?
I didn't miss the point. I gave you several reasons it's an invalid comparison. You just didn't understand them (and still don't). Smoking, a purely optional behavior with no function, is completely unrelated to driving a car, a usually non-optional behavior with a very specific and necessary function. That is literally the end of the comparison because nothing else matters after that.
The reason fatties and smokers are held to this standard is because they're making choices that hurt themselves and usually some collateral damage to others (health insurance costs, for example). You're right that people make bad choices all over the place all the time - a point I still agree with.
Should we look down on people who BBQ?
It depends. They're still making food, which is necessary, and some ways are better than others. This still makes it better than smoking in every possible way, but I think people should engage in cleaner ways to cook food if that's what you're really asking.
Should we look down on someone who owns a car that gets less than 40 mpg?
With no context, it's impossible to answer this. 40 is also too high, but if you said 20 I would agree as long as the person didn't have a specific business need.
Should we look down on those who would eat an unhealthy lunch at McD's?
Absolutely yes. I eat there once or twice a year and I would never try to defend that practice. I like it so I do it, which is the point you're falsely trying to make about smoking. If you smoked once or twice a year, you wouldn't be a smoker. If you eat mcdonalds every day, you'd be a 'smoker' and yes you would deserve a social stigma because that's fucking nasty and unhealthy. However, eating at mcdonalds can still be handled in a way that doesn't influence others nearly as much as smoking because the deleterious effects of mcdonalds can be mitigated with exercise. Smoking is pretty hard to counteract.
Notice I didn't say you should be barred from choosing to eat at mcdonalds because I think you should maintain your right to choose to do that.
