All true. But unlike the usual “racist!” epithet Liberals throw out when they feel the ground beneath their arguments give way, I and most if not all of us who are using the term here mean it in a neutral and purely descriptive sense.

Back in the 1950s, our math teacher in Yokohama, Mr. Yajima, was a German national who had served on the Russian front in WW II.
The Japanese who knew him found him perfectly acceptable.
