I believe (just as every qualifier in the article believes), genes dictate physical properties. The rest is the result of thought patterns ... taught and learned ... (because one believes a particular way or view is correct, one follows the paths that way or view directs.)
and are at pains to argue against the existence of inborn propensities toward particular behaviors (particularly sins).
Now, do you really, really believe that the normal genetic component of a heterosexual male human being does not produce a powerful temptation to commit fornication, and even fornication with women just past puberty? Yes, we sin by our own choice, just as Adam did, but it's a lot harder for us to choose rightly out here in 'this world' rather than in Paradise.
It's the wrong fight. Traditional morality is given us to transcend the temptations we are heir to, and grace to attain again the likeness which had fallen of old. Arguing that besetting temptations cannot be inborn goes against both the plain words of Scripture and increasingly against the evidence of science.
Fight for the morality given us in the Scriptures, not against science.
