Your point is? How come of the millions of us who grew up in the '70s, exposed to smoking at home, in cars, stores, at school never developed cancer from it? How come now that nazi pigs like yourself have forbidden any smoking in public places, that the incidence of childhood asthma has INCREASED? What if someone came to your house or car or business and found something they "don't like" you to do, and used the force of government to make you obey? While you're squealing with delight over other people's freedoms being taken away, remember that someday the same thing could happen to something you like.
Should you knowingly expose your child to a potential danger when its unnecessary?
