My bad on Asterix. The name still stands, however.
Still, I can't say I agree with this line of thinking. Words are created for each language for a good reason - they just work better with the people they're created for and their tongue. There's a reason why we don't say foreign pronunciations for, say, "spring rolls," even if the dish is something that clearly isn't created by the West.
Do you also call Japanese voice actors "seiyuu"?
