Well, no one would deny you your right to your opinion. Let me just say this... I am new to the breeding of leos, it fascinates me. Also you say that these people ask for a lot of money for their geckos..let me ask you this do you really think the geckos care? The reputable breeders I have talked with and learned from take the utmost care of their animals. If you research the posts on here almost all have adopted abused animals. I know their are breeders that abuse their animals and breed them within an inch of their life, but their are people that put babies in trash cans too. Should we stop reproducing too? We have laws against abusing animals just like we do for humans. Also if you research a breeder before you buy, it doesn't take long to find the ones that are just in it for the money. These people will not get my business. I have been watching this forum for many months now, even when I was in Afghanistan and Iraq(when I could) These morphs are not bred for money, but rather the adventure of seeing how far you can take the species. It takes years to isolate and breed a trait to the extent you see today, it doesn't happen overnight. This as you can well imagine costs money,time,and patience. Are some overpriced? Yes, I would agree with you there, but they are not making you buy them either. If I think a car costs too much I find it cheaper or I don't buy it. This is the greatest virtue of freedom and the capitalist system.
Breeders such as Rob Jenkins, Shayna Whitehouse, Marcia McGuiness, and KelliH love all aspects of the craft and love their animals. Marcia sent me two beautiful geckos and worried about them so much, when UPS told her no one was home at the scheduled delivery time, she bombarded my email with messages, worried about her babies safty. Of course my wife was home just changing a stinky diaper.
As I said you are entitled to your opinion, and you and your fellow postee's on here definitely are. I would think, however you need to do a little more research before you decide to tell people what they are doing is wrong. If we applied your reasoning to all creatures including humans, we would basically vanish from this earth. Remember you can find a dark side in everything. If you could see the joy these animals, that have been lovingly bred by these breeders,light up the faces of my three young boys you would be able to see the light and good side of this venture.
Ok I'm off my soapbox
