Here you can find a discussion thread about racism. It was started after certain article of Gregory Clark's appeared in Japan Times. The discussion took place in Gregory Clark's Google discussion group. After it has been going for 1-2 months(Dec'2004-Jan'2005), it was abruptly erased by Mr. Clark. Fortunately some people had archived a big part of it. Here you can read what is saved, and judge for yourself for the reasons Gregory Clark deleted the whole thread.
