The parts that we don't talk about much include the fact that a lot of mass breeding is done by retired or semi-retired people who found an honest way to make a dollar. There is also the fact that a mass commercial breeder can be a professional and still make good money. I'm convinced that it is quite all right for a commercial breeder to give the minimum number of vaccinations necessary, have the vet give a few litters of pups a once-over, and it is almost mandatory to sell in advance, a practice that just ensures homes for the animals.
Several of the high profile cases have been against owners of animals whose care was worked out with a veterinarian. I'm convinced that more than nine tenths of the evidence against commercial breeders consists of lies motivated by hate.
A question that needs to be confronted is, who said that it's wrong for breeders to make money? Worse, when did "good breeders" decide that a "good breeder" had to lose money? You know why the activists don't want breeders to have any money. It takes money to defend yourself against false accusations in court. If "good breeders" do it to themselves, they're driving themselves out of business and this helps the haters.
A "good breeder" wants to be at least one tier higher than a farmer. That's a little bit strange because the farmer gives us our life, all of it, every bit and scrap that we eat. Maybe a lot of us have a self-image problem such that we don't give proper respect to those who feed us because what's wrong with a Kansan farmer who would feed the likes of us? So this "one tier higher" means, figuratively, donning the robes of a penniless cleric who wanders the paths of India with a wooden bowl in his hand. There's something of the "selfless service" in all that, but I have to say that the person who gives a service to humanity and animals is worthy of respect and money. "Selfless service" is a hangover from the popularity of East Indian practices in English-speaking cultures and it is an insult to anyone who truly is doing good works. It's self-destructive. It might explain why India has myths (which they consider to be absolute truth) of wars that included the use of what appeared to be atomic bombs, destroying each other very badly over and over again for the last five thousand years.
If a dog breeder, or a lion breeder, or any other human being wants to be good, his or her worst enemy is going to tell them the absolute worst way to do it, if they allow it. Generally our worst enemies pretend to be those who are going to make us over in God's image, which contradicts the Book that says that we came that way out of the box. At the same time they claim that man's work is corrupt, they want men to make over what God is said to have made perfect in the first place. That's a swindle.
So we have to do what we should have been doing in the first place. Don't let the crazies tell us how to run things. Decide as responsible adults to resolve the moral questions ourselves.
