... I don't hate smokers, as smoking is a choice, and people have the right to smoke. That's just the truth of it, and the smokers I know have a wide variety of responses to anti-smoking, from "I can't stop, I'm addicted" to "I like to smoke" to "Lung cancer is bullsh*t". I run into "Lung cancer is bullsh*t" a lot. I don't really like it, as my mother died from lung cancer due to smoking throughout her life. She did not go peacefully, and everyone thinks that death will be painless. It's not... she was in terrible pain for the last year of her life, right up to the point where she begged us to pull the plug. Her passing was not quick, and after her passing, we've had to live with the decision we made.

I didn't mean to get all emo, but... yeah. =(
So, please don't say something like "I hope smokers die horribly and painfully", because many of them are already on the road to tens of thousands of dollars of medical bills and a bad fate. The smokers you hope will die painfully are still human, they are fathers, mothers, friends, lovers, and family who will never be seen again. I am even slightly offended by what you have said, but I will chalk it up to the fact you may not understand the sharpness of your words.
My mother was born and raised in Vietnam and she lived in hiding from the Vietcong until the war ended... then she came here, when anti-smoking education wasn't as prevalent as it was today. Anti-smoking education was non-existent in Vietnam when she was there. So please, do not wish ill towards others like that.

I am loathe to take choices away, but the best we can do is educate the people, and raise our children to know the truth. But in the end it's their choice, and it's unethical to take a choice like that away, unless it becomes EVERYONE'S choice.
