>>I don't know you, and I don't know what breed you show. It could be that you are not to be blamed, but I suspect you've heard these criticisms of what has happened to show dogs before.<<
My friends breed for not only "looks" as you call them-we call it breeding to the standard. We also breed for temperment, retrieving, birdiness, soundness,friendliness and most importantly health.
I think you're wasting your breath. There is a mantra out there "Show breeders have ruined this or that breed." It's pretty embedded into modern thinking, so I doubt you will do anything to erase it.
