I think it is just as insulting to demand the culture you are visiting to pronounce something unnaturally and incorrectly (to their ears and tongues) just to make YOU feel better. I would never think to go to Japan and feel upset that they pronounce Chloe as "Kuroee". They can't make the L sound, and it is not their fault, and it is rude and presumptuous of me to expect it of them.
