Okay consider this, there are psychopathic parents out there who torture, molest and harm their children causing physical and mental health issues the rest of their lives, wouldn't you want laws to protect these unfortunate kids.... Now passive smoking causes physical and mental health issues to growing kids but in a socially acceptable way... There should be laws to protect these kIds who have no other option but to depend on their parents. All kinds of laws affect the majority because of ignorant few without cOmmon sense.
