Brown Paper Bag Rule
In the years following World War I through the 1950's there was an unofficial/official rule that limited access to Night Clubs to Blacks that were lighter than a standard paper bag.
Fraternities and Sororities also used color to select their members. Guests and potential members were also judged on the straightness of their hair and the thickness of their lips.
But this kind of prejudice mainly played out in social groups where darker skinned Blacks were not welcomed.
It is interesting the lengths people will go to divide themselves into ever smaller groups.
This kind of Black on Black Racism has not disappeared. Spike Lee's movie ‘School Daze' highlights, although dramatizes, some of these divisions. For a lot of Black people there is hierarchy of Blackness depending on skin color. There is the assumption that the lighter your skin the easier time you will have in life.
When I was younger there was a ‘Good Hair' issue. If you were a Black female it was almost mandatory if you got pregnant get pregnant by a man that would give your baby good hair.
This always struck me as bazaar.
