Well, I guess you don't use the Bible when it compares the good and bad in animals in comparison to humans. Frankly we learn a lot of good and bad things from animals, and I agree with Carson on this one. Homosexuals try to use the tactic of animal comparison as well, but their reasoning is flawed in there way of observing animals. Carson's is not.
Actually, I do, Proverbs 26:11 was an example I gave. Using animals to picture character traits in a proverb is very different from using them to prove what behaviors are natural. Again, they are not using them in proverb or parable form to paint an easily understood picture. They are using very specific behaviors and saying it is natural to copy those same behaviors. Force them to be consistent in that view.
