I have a problem when people use this argument. you are basically saying that smokers have more rights than non-smokers and if non-smokers don't like they should STFU and stay home.
NOW who's rights are being curtailed? You suggest non-smokers only go to places where people don't smoke.
Is there anybody else you'd like to marginalize?
No...I suggested that people who have such a big problem with smoking should only go to places where people don't smoke. It's YOUR condition. I have a friend who is claustrophobic. Guess where he doesn't go? Would it be fair to force all car manufacturers to make their vehicles at least 10ft wide and 8ft tall because my friend has a problem with small cars?
Now, if a pool room opened that did not allow smoking (let's say one of you guys owned the place). And then JoeyA plays in a tournament at this pool room and starts complaining about how you should be able to smoke in a pool room and demands the owner change his policy and then demands that all venues should allow smoking...basically the same situation, only in reverse. How would this make any sense? Why does it only make sense in one direction?
The answer is simple: because you're biased. You only want it to make sense in one direction. But it's the exact same situation both ways.
