Slave owners relied on black sexual deviance to regulate and exploit enslaved Africans. Sexual victimization is often found to be a defining feature of American slavery. These acts were committed with the assumption that all Black people are heterosexual. Racism and hetero-sexism both rely on segregating people as a mechanisms to maintain racial and sexual hierarchies. Often times State maintained laws that did not punish hate crimes against LGBT people. These laws also failed to protect the LGBT people who were stripped of jobs and children. With little to no support the LGBT crowd comes out at their own risk. 

               The "norm" or seen as normal is being a white heterosexual male; many rights are distributed accordingly. Likewise  many punishments are handed out on the  contrary. Not until recently has homosexual marriages been accepted but not by the entire country only certain states acknowledges said unions. Heterosexual marriage is not the natural because natural things do not have to been reinforced and the same for interacial marriage. Being black and/or of the LGBT community both carry stigmas, LGBT for sexual deviance and blacks promiscuity, etc.
