You really opened up a can of worms with that question!
I am also against declawing. Unfortunately, (confession time) I was uninformed when we got our kittens and the vet recommended declawing Trent when we got him neutered. They didn't properly explain the procedure ("We just remove the shaft where the nail grows out of") and did not tell us about any possible future problems.
His paws got infected and we almost lost him. If I had only known then what I know now, I would never have done that to him. Fortunately, he doesn't have any behavior or litter box problems. I will never have the procedure done to any other cats.
I agree that it is better to have the cats declawed than abandoned (or in the situation that Bad Habit described), but I also think that if the only issue is scratching where you don't want them to, you can work with the cat to change the behavior.
