Ahh the old debate still flows but along a different pathway now.
Most of the "purists" veiws came about when some numbnut decided he would smuggle jags into the country, concoct a ridiculous story that they just randomly hatched from a clutch of his own and try to pull the wool over everyone's eyes. Yes, he got away with it, and now happily retires on his income from what many people believe, has stuffed the hobby in this country. We knew it would happen, and I've had conversations with people who bought into his animals, only to end up with a sick feeling in their stomachs after they witnessed the neuro in full flight and (considering the bio-security of our native animals was also pushed aside so these mongrels could make big money selling these retarded mutants) they decided to get away from the jags. Which probably, may be in part, nothing more then damage control.
Its not even the fact that a crossed subspecies is good looking or not, it's more the problem that many first time snake keepers who literally know absolutely nothing about nor even seen a wild snake, thought that breeding diamonds with jungle or bredli with gammon, was perfectly normal and they would produce great looking animals and make a fortune.
People who have been in the game since before jags, were split between money and ethics. But the outcome was always obvious, especially when other countries documentation of their hobby was available and even they were telling us quite openly their thoughts on us crossing our sub species.
Obviously, now, our hobby has been royally f'd over and many who were only in it for the " excitement" of keeping a snake have now realised that their really only another animal and there isn't that associated mystique that used to go along with them.
I'm sorry but, line bred 4th gen julattens will not be much like their wild ancestors at all, that is the narrowing of the gene pool that creates the nice look.
I will listen to the people who have their core focus as ecologists, over hobby breeders, regarding true to form, any day over hobbyists. Many of us are both, but unless you spend time in the bush dealing with dozens if not hundreds of wild snakes in a particular region, and not just listening to what the guy you bought your snakes from story, you can only be guessing or assuming whats really out there.
No offence intended to anyone here, just an opinion. My work has shown me that pretty much every pattern available in "pure snakes" in the hobby, has or would have occurred at some time in the wild anyway.
