Maybe in apartheid South Africa or the Old South. Their skin color will probably be somewhere between white and black. Why is such a child automatically considered black, in your mind?
If I recall correctly, Cyb is of mixed-race ancestry. I'd be curious to hear her take on this.
My father is white and my mother is West Indian Creole of mixed race origin herself. Here in America, there was the one drop rule that any black blood made you black for the purposes of slavery and segregation (heartily now championed by liberals!). South Africa a mixed race person is mixed race or coloured as more commonly know and the apartheid rules had its own peculiar set of limitations,etc.
Race is BS and made up by people with a deliberate agenda of their own.
