I hope you know that a quarter of us will die of cancer whether we smoke or not. Just because you know it is bad for you, and perhaps a relative has suffered from smoking, doesn't mean you should hate smokers. Thats practically saying you loathe those relatives who smoked. My Grandpa died 6 months ago from smoking related cancer, yeah i feel bad when i think how he'd feel about me smoking, but his death doesn't make me want to dislike smokers. I also love how many of you probably eat shit food, drink heavily, smoke weed and take other health damaging substances but hate on smoking as you see it as socially unacceptable.
I don't drop my fag ends on the floor or mountain, i don't smoke in restaurants and even when im at the cardroom i stop smoking if someone does not like it. Not all smokers are selfish. Grow up and stop making generalised opinions on people you don't even know.
