How to respond to personal attacks about owning a doodle?

[Camilla and Darwin]

I did so much research on what breed of dog to get, I was shocked when I started getting attacked for being ignorant. As soon as some people hear I have a doodle they go on a rant about not buying designer dogs, how he is nothing but a good for nothing cross breed, you shouldn't pay money for a cross breed, I should have done more research, etc. I feel so frustrated because I considered both purebred and crossbred dogs in my search, and did extensive study on the Goldendoodle breed. Yes, I know they are a cross breed. (I do not feel that only purebreds are worth money. That is ridiculous! A worth of a dog should not be determined by pedigree) I also know that they can be unpredictable as far as shedding, size, temperament, etc. I try to calmly explain this to them but it's as though I have morally offended people. Do you get the same response from some people for "buying into the designer dog craze"? How do you respond?

Funny when I took my labradoodle Baxter, to the vet for his first visit, he started telling me how he was a mutt, half breed, and the breeder "saw me coming" blah blah blah. Then he said I love Standard Poodles and I love Labs, what a great combination I wish I had thought of mixing the two. Baxter was the first Labradoodle he had seen and every time we go in he always says what a great dog he is. All of the negative comments I have received have been people joking around.
