So, is he saying they are born that way or it’s a condition that come on over time (like high blood pressure, his example)?
It doesn’t really matter. It’s a defect, and it’s for the good of the person in question to correct the defect.
Of course, the gay activists like to say that gay people are born that way, but even if they were, they still need to get fixed.
I think it could result from some sort of chemical imbalance, but most likely it’s psychological. Absent or neglectful father being the commonest cause.
Either way, it really doesn't matter -- "be ye transformed by the renewing of your mind."
