In a case like that i hope your friend didnt buy the het ghost. If you ask a question about the animal for sale and the breeder does not give you an answer, thats just as bad as giving the wrong answer. Makes me wonder how many people out there have been duped into buying hets and got normals. The biggest problem i see with that is the over abundance of normals. Another problem is how to classify that animal. How do you know if you were sold an actual het animal that you just keep hitting bad odds on, or if its really just a normal? Then your stuck with something you cant sell for more than a normal even if it IS a het.
The people purposely passing on wrong info or lying about their animals are the ones i have an issue with. The ones that ask questions and try to educate theirselves are going to be the better breeders/keepers.
The ones who answer a question wrong should not take it to heart if they are corrected. They should learn from it and stick around to learn more. I agree that people should not bash, but correcting someone in an intelligent and nice way should always be done.
