Regarding Gregory Clark's Jan. 15 article, "Antiforeigner discrimination is a right for Japanese people": I presume the author does not anticipate ever desiring to use the "bathhouse" mentioned in the article, or he does not have a problem with being excluded. Perhaps he has the illusion that he is one of the "good foreigners" and won't be subjected to the same treatment as those Russian hooligans.
Many people in the United States had no problem with "Jim Crow" laws, but few would justify them now. I also wonder what would happen to my son (whose mother is Japanese, has an appearance that is decidedly Western and is a Japanese citizen) if he tried to enter that bathhouse.
A word of advice to Japanese: Before establishing exclusionary rules toward foreigners, consider how you would like to be treated when you or your friends and family visit other countries.
