I absolutely agree that people should have that choice and that they do not have the right to decide that for others.
Do you? Really? So should people have the right to work in an office where smoking is allowed? Eat in a restaurant where smoking is allowed?
Sure, but smokers are now a minority. If the majority vote to ban smoking in the workplace and restaurants, there is no longer a question.
Smokers are free to smoke where others are not breathing.
And no one has the right to force me to smoke at my work or public places.
Majority of people did not voted nor decided. Politicians did.
