> My understanding is that they are using it jokingly

That's what "making fun of" means, no?

> I agree with >>141. I mean, you always hear us talking about "those crazy Japanese," but do we really care about their use of our language?

We care to the extent that we like to make fun of them. That's all I said they were doing, too.

That was my whole point. Sling said they "don't care", I returned that they care enough to make fun of it. If they didn't care, they wouldn't joke about it. We care about the Japanese mis-using English to the point that there are websites devoted to it. We don't care about many other languages mis-using English (and many do), so we don't make jokes about those.
