*Black Privilege (noun):*
When benefits, rights, and privileges gained from African American struggles, sacrifices, and activism are transferred to and enjoyed by non-Black individuals and groups, often perpetuating systemic inequality.
"Black Privilege should mean equal rights and protections under Civil Rights Act 1866, but ironically refers to the unfair advantage other groups have claimed from laws originally intended to benefit African Americans."
OR alternatively:
"People realized too late that Black Privilege actually meant others benefiting from laws meant to end Black oppression – a twisted systemic inequality."
OR simplest form:
"Black Privilege: when laws meant for African American equality are exploited by others."
