Tian reminded me that while the missionaries might say that Japanese was the work of the devil, they have no problem with Chinese--in its written form, at least. Check out his post on HanziSmatter about the World Bible School's crackpot theory that evidence of Christian theology is to be found in the composition of Chinese characters (which ignores the fact that characters contain semantically irrelevant phonetic elements and the existence of loan characters, etc.). Tian also writes that according to SmartFilter, the World Bible School (World BS for short?) site is classified as "phishing" "criminal skills." Too bad it's not classified as "Bad Sinology."
