The most intentionally abnormal creature on Earth is man. Even chemically confused bulls don't try to tear the unborn calves from the wombs of the cows they inseminated. There are many instances of abnormal behavior in animals that scientists try to cure instead of excusing it as "enculturization" like they do with humans. We know that same-sex nest sharing among adult birds is counter-intuitive to that specie's continued survival and that it is not normal.<quoted text>
You still have no examples for anything that is actually "normal" about living organisms. Try harder, one day you may just see reality.
Too bad you try so hard to excuse your own aberrant behavior within a twisted sense of reality. Keep twisting, maybe you'll torque something back into its correct position.
