Should albinos, hybrids, etc. be discouraged?

I thought it would be interesting to start a discussion regarding the stewardship of PDF's and their breeding, etc. Coming from keep aquaria (both fresh and reef), over the years I have become much more of a hardlined 'purist,' so to speak. I don't keep anything that wouldn't most likely be found in nature under that same form. Various crosses, hybrids, and albinos are immediately off the list for me. The freshwater aquaria hobby is amuck with all sorts of comedic fish species, and unfortunately, people are trying to do the same with marine fish (luckily, rearing larval marine fish is slowing this down to a large degree). However, there are some who are trying as hard to possible to preserve solid bloodlines and prevent crossing (rainbowfish hobbyists, for example).

With the understanding and realization that many of the species we keep are becoming more and more threatened in their native habitats, what is your opinion on the amount of responsibility we have in breeding our frogs and keeping them as close to their wild counterparts as possible?

(This discussion was rolling on Frognet for a while, and I think turned toward possible breeding guidelines within the hobby...but I'm not sure how it turned out. Maybe someone here who saw it all the way through can shed some light on the subject).

Your thoughts?
