You know, I think this whole concept of "donuts" is a bit overblown. Just look at the Pokemon World; is there anything that is different there from our world? Hmm, I dunno, maybe the fact that the whole world is inhabited by supernatural creatures that have the abilities to spit fire, freeze water, and create earthquakes?
To use one of Dogasu's expressions in his own comparisons, I think the whole fuss over renaming a rice ball as a donut is just missing the forest for a tree. Sure there are similarities between the worlds, but there are a hell of a lot of differences too. And when you compare the concept of a Pokemon with a real animal, calling a rice ball a donut really isn't anything like the big deal it is made out to be.
Yes the consistency in the translation would be nice, but who's to say that in the Pokemon World a donut doesn't look like that? (And yes I'm aware that they are in fact called by their proper name in the raw, I'm talking about the slightly different universe that the dubbing has established; humour me).
People complain over the discussions on how much music was kept per episode and blah blah blah; complaining over whether a rice ball is being called a donut or not is just as nitpicky and annoying.
