Really. Decisions people should be free to make - poisoning themselves, killing their children. Decisions people should not be free to make - educating their own children, choosing their own medical care, spending their own money. 
Hmmmmmm, my parents smoked, my grandparents smoked, my great grandparents smoked, I smoke, yet all my children and grandchildren are as healthy as a horse before the Kentucky Derby! I don't think they poisoned me, and I don't think I poisoned my children or grandchildren.
Every one of my ancestors lived to be older than 75! Wonder how come, since we have been poisoning ourselves for generations!
Maybe I should sue the tobacco industry for prolonging our agony!
