There's levels.
I wouldn't let her say the n word
But I wouldn't call it bucking if a black guy wifed her either.
But when somebody like her also has a white husband, then they are white.
My rule was always if you bi-racial then your race is the race of your kids.
Example;
Tia = Black Woman
Tamara = White Woman
Jesus Christ I cant front though. If a biracial claims Black, as most if not all of the ones I've known throughout the years, then as far I'm concerned they're Black.
