One early proponent of the “born that way” thesis, Michael Bailey, conducted a study on a large sample of Australian twins and discovered to his chagrin that the concordance rate was just 11%. Peter Bearman and Hannah Bruckner, researchers from Columbia and Yale respectively, looked at data from the National Longitudinal Study of Adolescent Health and found concordance rates of just 6.7% for male and 5.3% for female identical twins.
It doesn’t matter. Even if the are born that way, it is still a disorder. When a child is born with diabetes, we do not say that God made them that way and celebrate it. We treat the diabetes. In this sinful and fallen world, people are born with disorders (dont get me wrong, I do not think they are born that way, but even if they are its a fallacious argument)
