I have also removed the factual dispute, original research, and missing references tags as I believe my deletions have addressed all of those problems.  Note that there are many references to various primary source media inline and a handful of URL links, too.

I am also particularly suspicious of this passage:

In a 2002 Pew Research Center poll, 96% of white Americans claimed to have used the phrase in a "playful manner", and 94% had never previously considered the phrase to be an ethnic slur.  However, 34% of Asian Americans believed it to be racist language.

Note that a search for "ching chong" on the Pew cite fails, and there is no record of such a poll anywhere else in Google apart from Wikipedia pages.  Also, the numbers don't add up at all. ←B4
