I'm not going to get into any debate with you, H-B. But pornography has been around long before the Internet. Maybe the Internet just makes it easier to access.
I agree that I have evidently overemphasized the existence of sexual monogamy in animals, now that I have read more about the issue.
As I mentioned before, I still have my strong personal beliefs, based on my religious principles. Yes, if people have other principles, then they can do differently, if it's something that they agree upon.
