Why do people think Japanese anime mocks black people?

I mean take Mr Popo for example. WTF? If anything INDIANIANS should be offended. What black man wears a turban and a purple vest? And Jynx, that was a reference to the Ganguro girls. If you don't what that is, look it up on Google. And if read the recent Naruto manga, tell me what you think of this idiot.http://www.youtube.com/watch?v=58PEXyOwB9U&feature=channel_video_title
