It's more of a matter of not subscribing to the view that your actions and history is irrelevant, and that your genes is all that matters. People who are born in Japan by people who are Japanese citizens get called Gaijin, even if it's as little as being half-gaijin genetically, or several generations after your ancestors immigrated, as long as you have tell-tale marks of even a fraction of non-japanese genes.

Civility really does matter, being called foreigner by someone who doesn't know you isn't odd, but to be called Mr Foreigner behind your back by someone who's e.g. been your co-worker for the past decade, in spite of that you were born in the country (though perhaps by one or two citizens who had genes from elsewhere), is retarded. If you grow up in a culture, being integrated and assimilated as what most countries like them to be, why are you to be denied the right to be seen as much of a person as someone who's family tree goes back thousands of years in the country? Your family tree is not you, genetical heritage is not automatically cultural heritage, even though many seem to want to kid themselves about that.
