I think so many people (myself included) are uptight about "certain" hybrids because in many cases, people are breeding species together that would never encounter one another in the wild, thereby "playing god" if you will. There's a reason these animals evolved the way they have. Just because you can do something, doesn't mean you should. Don't get me wrong. I'm all for hybrids that encounter one another in the wild naturally.
