No, Barb, it's a perfectly legitimate concern. I'm a tremendous proponent of purebred dogs, I love participating in conformation shows, but I (and others) have concerns about where we, as a fancy, are headed, particularly in certain breeds.
It is my understanding that, because of their peculiar anatomy, natural mounting, mating, and tie are significantly unlikely to happen in the Bulldog without significant assistance by humans. You can google "natural breeding bulldog" and find a few sites that discuss this. In addition to issues of geometry, the male, if he must make numerous attempts to mount (as is often the case for any male dog), is prone to overheating, which can be quite dangerous in this breed.
Once you've managed to achieve a pregnant bulldog bitch, getting the puppies out is in itself a hefty proposition: again, the anatomy that has been selected for by breeders (very large head, narrow hind) makes a planned c-section delivery necessary in the majority of cases.
Bulldogs did not always have this peculiar anatomy; like the exaggerated hock-walking gait of the German Shepherd and the breath-restricting flat face of the Pug, breeders, with the help of the show-ring, have selected for certain traits to the point of exaggeration.
Please note that I see nothing wrong with selecting for certain traits in a dog. (A long-faced Pug wouldn't really be a Pug, would it?) It is the exaggeration of these traits to the point of detriment to the dog's healthy function that is of grave concern.
Unfortunately, when these concerns are brought up, the "old guard" of those who have the most powerful voices in the American dog fancy begins to fling accusations. My opinions are, as far as I can tell, most unpopular among the dog show set - people want to continue doing what they've always done, and few people want to sensibly address the problems that are becoming more and more apparent.
Again, I reiterate: I love purebred dogs. I love dog shows. But I have no love for the disturbing trends of over-exaggeration without regard to good health that are apparent in many dog breeds.
