I havn't had time to read ALL the replies, but I actually know the author of the original post, it was copied and pasted as a new post from another forum, and the forum title was Purity Debate.
The original author is well known for his stance on being able to do whatever you want with whatever you want....and to make it clear he is in the United States and was refering to U.S. captive breeding of Australian pythons.
My personal opinion...
The issue many so called "Purists" have is that we have a VERY limited gene pool of what we all consider "Pure".....and it seems the term "Pure" upsets many people....and I really think they are taking the term "Pure" out of context in a way...
What the term Pure means to me is something that does not have purposley mixed blood in it....we all basically in our minds at least here in the States have this mental picture of what each subspecies of Morelia looks like...we might have our own little tweek of what we like, but there are general characteristics that we all can agree on that make up each subspecies...ie...what are the characteristics that make a Classic Coastal different than say a Diamond or a Bredl's....
Sure NONE of us have proof of anything...but with our limited gene pool all we can do is continue to try and recreate these "Natural" differences...But recently say in the past 10 years...there has been this massive trend to try and create something new...people seem tired of selective breeding for color or trying to make the best example of that subspecies...and now its all about what can we create...
Now I have no problem with extreme hybrid/intergrades....ones that look really strange/unique/different....can't be confused with any certain subspecies...What I have a problem with is the high % hybrids/intergrades...ones that have been bred to almost resemble a certain subspecies...
I think that is the biggest hardship for so called "purits"...there are many examples...Bredl's and Diamonds come to mind...There are people who work with high percentage diamonds...ones that are JunglexDiamond crosses, or CoastalxDiamond crosses...now at the 50% range...most of the time its more obvious...but when they start breeding those 50% to say another diamond...and producing 75%ers....and then again to make 88%.....they start looking more and more like true Diamonds....
Now Diamonds seem to be one of the more harder to get species here in the states...now we have to battle if they truely are real diamonds....I have had MANY friends who purcahsed diamonds as Diamonds...be knocked as not being pure....So people might knock purests...but there is a reason...many are so vocal...
What purists do...in breeding for certain natural looks....ie "Pure"....is they try and keep things pure...no other way of putting it....it does nothing to hurt anyone...but ensure that future generations of herpetoculturists can have the oppertunity to work with Coastals, Jungles, Diamonds, and Bredl's.....where when people breed whatever to whatever...those offspring go into the US gene pool of muddiness...where post after post say "I just got this Carpet...what is it?"....then we have to guess what it most looks like....time and time again...to the point where many times morelia subspecies are just labeled "Carpet Python" and not given any subspecies identification...cause nobody knows...its just a mutt...aka "Carpet Python"....
I have kept both hybrid/intergrades and so called "Pure" or Natural look....and I have many friends who work with both...and its a debate the has no end...it will keep going forver .....or at least untill Australia drops the export ban...lol
Its funny as the most vocal of both sides, never stop to see each others side...the future as I see it is the Hybrid/Intergrade keepers and breeders will continue to do what they do, and the so called "Purists" will just have to deal with the unkown...and continue to try and recreate those characteristics that make that natural look or as they call it "Pure Look"...
Breeding for the "Purest" you can get doesn't hurt anyone down the road...but the known mass production of crosses/hybrids/intergrades....does affect the ability of "Purists" down the road.....We can't get fresh bloodlines here in the states, If someone wants say....a Diamond they have to take the word of the breeder that his stock is "pure" diamond...and not just high%JunglexDiamond crosses....
But To each his own....Sorry for the long post..
