It's quite easy to find that the 1993 EPA report that classified SHS as a Class I carcinogen has been vacated by a Federal judge and refuted by the Congressional Research Service.
So, since you are obviously one of those smokers who doesn't have the common courtesy of a farter, you choose to believe that a judge with absolutely no scientific background, or that Congress is more qualified to render a scientific finding, than 34 scientists (that's the number that I recall was bandied about when the judge made that ruling) and numerous assistants with scientific training. I suppose that if a judge were to vacate gravity, you would float away. And don't forget that Congress is still on record as saying that Marijuana is addictive and that has been proven incorrect many times over. So, who is the one who is really biased?
Unlike you, I admit that I'm biased. I'm biased because I want to protect my health and the health of others who have chosen to take care of our bodies. Your bias is because you not only want to destroy your body, you obviously don't care if you take others down with you, if it means that you will be "inconvenienced" by having to walk 20 or 30 feet to the door to do it. We can't have you be "inconvenienced".
If you want to kill yourself, go right ahead. I won't try to stop you and will even defend your right to make such a decision (even if you have to get the help of a Dr. Kervorkian type to do it). It's your life and neither I nor the government should pretend to know what factors may have led you to want to end your life sooner, rather than later. But at least, have the common decency not to act like a stupid terrorist homicide bomber, taking as many others with you as possible, when you go.
In the mean time, you might try to brush up on the meaning of courtesy. Among other things, it means that if you have to fart, you should go outside, or at least to a bath room or other unoccupied room. If you have to take a leak, you should get out of the pool and find a toilet. And, if you want to smoke, you should go outside. That's because non-smokers find your smoke just as offensive as your farts or urine in the water.
It should be noted that if most smokers were as courteous as most farters, we wouldn't need laws to prevent smoking in restaurants.
