There are a host of interracial family members who post regularly on FR.
I'm one of them. A Southern whiteboy/Indian married to a half-Japanese/half white California girl.
Totally agree with you that it's just not that big an issue anymore.
As near as we can figure, Tonto Junior carries the blood of the Choctaw Indian tribe, Japan, Netherlands, England, and Scotland. Maybe some French, but I refuse to acknowledge it.
I redeem my little bit of French blood by saying that my ancestors were the ones smart enough to get the heck out!
