Maybe you could clarify the wording for public view. I believe that the person who wrote the answer to which you are referring was thinking about people who claim that they have a genetic predisposition towards being homosexual. They often state that it is obviously God's will that they are homosexual because he made them that way. Therefore, homosexuality cannot be against God's will. He made them homosexual.
Some science makes the claim that certain people are genetically structured to be homosexuals.
The same claim is has been made about some people being genetically structured to be obese or easily addicted to alcohol. What needs to be understood is that God does not make illness, sin, or genetic or chemical imbalances. The sin that Adam and Eve brought into the world is what corrupted the world. God is not responsible for sin. Therefore, it is a result of sin in the world that a person may feel that he or she is predisposed genetically to be a homosexual.
