I do dissagree with your statistics, with regards to children being born deformed due to the affects of general smoking. I believe you said if you smoke your child has a 20% chance of being born deformed? so 1 in 5. I know multiple parents who smoke and have given birth the perfectly healthy children.
The population of england is around 61 million. 22% of its population smoke so around 12.4 million smoke. Use your 20 % data on chances of having deformed children being a smoker that makes 2.4 million. Half that to get the birth estimate and you have 1.2 million deformed children in england as a result of smoking. thats abosolute toff if you ask me
I believe your data charts are not accurate at all.
but with regards to the argumen, if two people love one another that much they should have the right to do what they want, not to let society an peer pressure control there actions.
Good topic!
