On boas:
But due to many greedy people out there who just want to make a buck you can't tell were most B.c.i are from.
Is this referring to central american vs. colombian and the different regions therein? That doesn't even belong in a debate about hybrids - whether a bci is from central america or northern colombia, etc., it's still the same species and same subspecies - akin to lamenting the fact that your corn snakes are a mix between corns of different regions. IE - a locality debate, not a hybrid debate.
And why is it because of greedy people? (Which implies that both they knew where the snakes came from, and they thought it was best to breed them to snakes from the same area, but didn't because they wanted more money.)
I'm not arguing that plants have been hybrides for centruies to our advantage but I think this is a little different most of those plants are not endangered.
So it's ok for plants, which most are not endangered, but it's not ok with corn snakes and king snakes (which you acknowledged that they aren't near being endangered). So all snake hybrids are 'bad' because there are some that use endangered species, and some dishonest people who try to pass them off as pure. Talk about punishing the many for the acts of a few.
Personally, I don't really have problems with hybrids, provided that:
1. They are honestly represented, no matter what % hybrid they are (I would prefer to keep hybrids visibly different, for 2 reasons: difficult to be passed off as pure, and what the heck is the purpose of a snake that -looks- just like a corn, but isn't?)
2. Not being released into the wild (I feel the same about pretty much any captive snake, morphs especially)
3. The snakes being used in the creation are not especially rare in nature or captivity (don't want to jeopardize the existance of a species)
If someone were to come up with a registry (like the AKC for dogs), you shouldn't have to worry about buying a hybrid.
