Well, I entered my state of being--although it's not such a clear-cut matter. Now I think it will be clear that your definition of what a 'true' Japanese person is, is, your definition--I will hold with that definition for this poll alone.
I am kind of Japanese in a sense, because environment does have some influence on the neurological matter--and not just heredity alone. However, I was born in California, USA; grew up in Alabama, USA--until after my first year of college, then moved to Arizona, USA; before moving here. In the meantime I had had the privilege of living with people from Mexico, India, and Japan. I had the opportunity to spend some three years working with Chinese--from the mainland. So...what am I? Does it really matter?
Yes, it matters, ASIAN Hero san !!! It matters very, very much. I am exactly the same as you !! Did you know that? I am every bit a human being as you are--or as any and every person living in Japan is. You see? It matters that we are all human. . . and that's where is stops.
I'll again remind you of what Dutch Baka has said above; PLEASE, lighten up a bit...it's only been two days, now.
