I wouldn't say the `vast majority` are `filthy, torturous, destructive, and unethical`. While that is undoubtedly out there, is sizeable, and should be addressed; it's far from the vast majority. You have to remember that these are still people raising these animals and that most people aren't monsters. They feel compassion and often aren't given a fair shake. Even the calloused, hard-ass, old-timers get teary eyed in certain situations. Hell, a lot of them don't like going to the zoo for ethical reasons.
