While what you are saying is partial true, the picture of genetics vs nurture is much more complex. I would recommend a excellent lecture series at (https://www.youtube.com/watch?v=NNnIGh9g6fA&index=1&list=PL4...) which goes into quite into depth about the subject.
For example, while there are clear differences at birth, nurture can permanent shutdown genes. Additionally a lot of activators for genes are triggered by mental thought process and the environment around individuals.
To make a car analogy, we could assume that faster cars are more often breaking the speed limit than slower cars, and we might very likely find this to be true in practice regardless of the actually speed limit. From there we need to be careful to conclude that its the fault of the car when a driver choses to ignore the law, or that just because the acceleration is faster and it is easier to drive fast in a fast car a person is not conscious in their choice.
