Identity formation for Black people of mixed origins follows similar identity formation for Black people (presumed to be unmixed), but can often become more convoluted. Some of the variables are more intricate, and there are other kinds of social pressures to take into account. (Once again context is critical). Partners and children in relationships that cross racialised group boundaries have to negotiate between both sets of families, and their opposition to the relationship; they have to circumvent stereotypes about the sexual motivations of Black men and white women, and what that says about Black men's attitudes towards Black women, often including their mothers; they have to negotiate how the white women in such relationships are seen as social outcasts at best, prostitutes usually, and the presumption that something must be wrong them if they want a Black boyfriend.
There are also the nasty names, the offensive stereotypes, the expectations that one must prove how Black you are; as in 'half-caste' and 'half-breed', the presumption of biological degeneracy, the questioning of your political commitment. The history of Black people of mixed origins in Liverpool, and Britain's other seaports, provides sufficient evidence of trauma that has frequently been an inescapable component of a mixed identity in Britain.
