There are more and more ball python morphs that seem to have issues/defects that affect them like wobbles, duck bills, potential for kinked spines, breeding problems etc. Years ago I got rid of all of my champagnes, sables, spiders etc because I didn't want to deal with the neurological issues. I know that most of these aren't that bad and many people think they're 'cute' and 'adorable' with their little quirks but I've had spiders that really were complete train wrecks and they kind of ruined it for me. But just because I don't like spiders does that mean I should warn others away from them?
I guess as long as people know the risks, I think it's fine. If people DON'T know the risks, I'd have to ask why they aren't doing their research first before buying the animal.
(I don't like bulldogs either, I think they have so many health problems that I don't understand why anyone would intentionally produce them. Yet, they command high prices and have a large following.)
