Other natural abnormalities include blonde hair, blue eyes, and the ability to roll your tongue.

There is no segment of humanity wherein a couple hope their child is gay. And no person in their right mind would want to be gay IF they were given a choice. Most significantly, homosexual sex cannot produce offspring. As well, I believe there are probably consequence for children raised by same-sex "parents".
I would consider homosexuality a natural and
undesired abnormality just like dwarfism, for instance, is a natural and undesirable abnormality.
