I am very aware of the history of the Japanese with the Ainu, the native Okinawans , and in Korea and Taiwan (and in other countries, as I have said).

The broader point that I am making, outside the specific instance of the Japanese which you seem to want to fixate on, is that xenophobia can be a useful social trait, to avoid a society being overwhelmed by a foreign ingress. This could work just as well for the Ainu, the Okinawans and the Koreans (and I'm sure they exhibited it too, but unfortunately weren't in a position to act on it strongly enough to defend against colonisation/vassalisation).

I'm clearly pointing out that you were wrong about the definition of xenophobia, and that the xenophobia of Japan was the seed for a fascist genocidal rampage. I would further argue that fearing people perceived as foreign which is what xenophobia is, is not necessary to establish and protect sovereignty or to hold close and nurture cherished cultural institutions.

I'm not fixated, I'm pointing out that xenophobia is actually bad and leads to bad things.

Every organism must have an immune system which is essential to (but does not guarantee) their survival. Just the same, a society has xenophonia as its immune system. That does not make it 'bad', even though it can produce very ugly effects.

I do not agree with your expansion of xenophobia to the behaviour of a people outside their own country. I do not agree that xenophobia is objectively bad. I also do not agree that "the xenophobia of Japan was the seed for a fascist genocidal rampage" and I doubt that many, if any, historians would agree with such a simplistic assertion either.

Since you seem to have a very closed mind on this subject (i.e. xenophobia == bad, bad, bad) and further discussion seems pointless I'll leave it here.
