No of course she's not a real person, but yes stereotypes do matter (sorry that this is off topic) they cause horrible generalizations (part of the definition) and can very easily cause racism. For example what it sounds like you said, and you've defended not denied of apoligized for. All japanese men are filled with lust and dream their whole lives about boobs. And saying that is horrible so I do have a problem with it.

But yes I agree that's how the artist's made her and she should be judged based on her character (she can still be called a monkey but I'd disagree).
