Re: bah, humbug, and it's the 60s, not the 70s.
As someone who grew up with his family referring to themselves has having Indian blood--yep.
Not that you would be able to tell by looking unless you are some sort of expert, but I'm 1/8th. Enough to be registered in most tribes. And all of the offendedness in that direction drives me crazy.
I am SO waiting for someone to correct me when I say I'm 1/8th Indian--except that it's not the sort of thing that comes up in conversation BECAUSE IT DOESN'T MATTER--unless some *#$#*$& starts pushing some BS Marxist theory of oppression on me.
