I think you are proving me correct then. The other 'something' is clearly not material since we are able to deny our physical or emotional inclinations.
Yet another painfully obvious fallacy of the excluded middle argument from you. There is a vast body of things which are not our DNA, including our evironment, and the chemical and physical structure of our sterling selves we inherit from our mother, which affect our behavior. The fact that we can make choices is not automatic proof of the existence of either God or transcendental morals, last time I checked.
Wait, wait. No you are saying all is not our DNA. Before you admitted that we can indeed suppress our inclinations. So where does this 'suppressing of inclinations' come from then? You have discounted DNA and the environment just does not cut it as the suppressor.
