and probably not the other.

Gender is also a pretty clear distinction (though not always entirely clear) where race is partly biological but largely defined socially.

Personally I don't buy into identifying oneself along lines of racial, religious, regional or cultural identity but I don't begrudge people who do either. So it's hard for me to be up in arms or have open arms about someone wants to be "transracial," if that's going to be a word now. I just say be who you are, if you feel that person has lighter skin or darker skin or speaks with a certain affectation, OK, but understand that not everyone will be receptive to that.
