I remember a time not too long ago, when the 1 drop rule was rightful considered racist. Any hint of black and you were branded figuratively speaking. Now, it seems that it is accepted and encouraged (Halley Berry comes to mind) so that those who can pass as "white" can get special treatment of sorts, socially or otherwise.I've said it before and I'll say it again: she may be recognised as black in the USA which has a unique history regarding race and where even one distant relative three generations back with a certain ethnicity seems to qualify you to claim that ethnicity (which has never sat right with me), but in much of the rest of the world the way she presents as an adult, she'd be considered white. Especially in actual black majority countries, even ones with troubled racial histories themselves such as SA.
Another thing that gets up my nose, is this attitude that whatever happens in the States, is applicable to the rest of the world. Each country has their own unique experiences and circumstances.
