Who's to say that colubrids, or any other snake in captivity is a true pure bred, to begin with? Who's to say that somewhere along their bloodline, some sort of hybridization didn't occur in the wild?.... If your against hybrids, why not be against color and pattern morphs as well? Majority of the color and pattern morphs would be more detrimental to a species survival (especially in the wild), than a hybrid would. Hybrids on average, are stronger, grow faster, and have killer appetites. Their health is incredible to boot... Now look at morphs such as the albino.....Tell me what that's doing to the specie, other than adding a rare gem to someones collection...
As for me, I love hybrids, and intergrades. I cannot get enough of them!
