Okay, I'll bite. I am a fucked gaijin and when I am discriminated against in Japan I do not mind because I understand their situation. In fact, I would do the same thing if I was in their shoes. Here are some facts. Japanese people are docile, especially younger ones. Foreigners can easily take advantage of them and many in fact do. Many robberies in Japan are commited by foreigners. Walk in Shibuya and tell me how many Middle Eastern characters sell phoney telephone cards. In fact, in Shinjuku and Shibuya (maybe other places as well but I only know of these two) I guarantee you that if you spot a MIddle Eastern person, he is probably overstaying his visa and is engaged in some shady business. The only other sad part beside them being shady is that the bastards usually have a pretty J-chick with them all the time.
So what I am saying is that Japanese people cannot protect themselves against the charlatans so they must take more unconventional actions.
Okay, let the punches roll....
