The question really stands: Who is to be really offended by those funny names.
I'd agree there is something that could be considered blatantly racist about them. But here is the thing: The U.S Press (specially TV versions) were so eager to have last-min information, that they felt in the usual trap of never verifying information before shooting out loud as veritable, and valid.
Someone joked on the press with those silly names (with an attempt to sound Asian-name like), and the 24h news channels promptly ping those back.
It left a trace of "how much thought" is put on those fastly transmitted -onthespot- type of news.
That's where the offense, I think, really reside.
And also, offensive, to the public that is treated with that much disregard to personal intelligence by those same channels
It's really, hilarious, and offensive -- but in unpredictable ways.
