Is the following acceptable? 

 :::Most Japanese historians believe that the Nanking Massacre has been substantially exaggerated  by the Chinese government in order to damage Japan's reputation in the world community. The most extreme view held by some in Japan is that the Massacre was fabricated. In China, the event is a major focal point of Chinese nationalism, and to this day stirs great passions among the Chinese people. Japanese attempts to moderate Chinese claims are rejected as historical revisionism. 

 (I noticed a second problem with this sentence in the original: "The (relatively benign) Japanese version of the incident is considered to be historical revisionism, especially by the Chinese." This implicitly incorporates the claim that "the Japanese version is considered historical revisionism", which is definitely going too far!) 

 Please let me know what you think. I'm not sure if I've gone too far the other way.
