Racism in the Japan Times

The Japan Times commenting policy says

"Don’t disparage a person’s race, religion, color, gender or sexual orientation or generalize about a nationality or race."

Many of the posts here "generalize about a nationality" (mine, which is Japanese) in an extremely negative way.

Where are the moderators? Or is it forbidden to generalize about every nationality except Japanese?
