So if we try to breed smaller ball pythons.. that's not okay? How is that different from breeding albinos? As long as the end product is healthy, I'm not sure I see a real difference.
I think the different breeds of cats are a better example. Dogs originally were bred for specific reasons, for use. Herding, hunting, retrieving, guarding..
Cats were bred as companions, and for pleasing colors and combinations of colors. So a persian is like a albino, there's no reason for a flat faced, full coated cat, other than we find it pleasing. Likewise, the only reason we breed pastels rather than normals is that we find the color combination pleasing.
As long as the snake is healthy(no one-eyed turtles please), I'm all for morphs.
