I read through that. Can't say it wasn't painful. Yes, the editor of that forum apparently wants all non-white people exterminated - except for the Japanese and the Ainu who he thinks are cool.
Revolting as this position is I don't think holding it should disqualify anyone from editing Wikipedia. I admit that I feel squalid saying that but it's the logical result of my principles and I'd prefer not to abandon them.
Then again H.G. Wells advocated much the same idea (without that wussy exception for people living in Hokkaido) and I don't mind reading his books. Maybe I should.
