"Afro-X" - A shirt with a double meaning.
The First meaning is about the many ways we exist in this world. We are everywhere. Solve for X.
From Wiki - "The term Afro-Latin American refers specifically to people of African ancestry and not to European ancestry, such as Sub-Alpine European white. Normally Afro-Latin Americans are called "black" (Spanish: negro; Portuguese: negro or preto; French: nègre or noir). More commonly, when referring to cultural aspects of African origin within specific countries of Latin America, terms carry an Afro- prefix followed by the relevant nationality. Notable examples include Afro-Cuban, Afro-Brazilian, and Afro-Haitian."
The Second meaning is a political statement. Malcolm X dropped his inherited last name because his true family name was lost due to slavery - in this context African-Americans (Afro-Americans as we were once called), have severed connections to our ancestral home countries. "Afro-X" also speaks to the disconnection a great number of African-Americans feel to this country's ideals and institutions. They were not created with US in mind and they are not operating with our needs in their practices. So "X" conceptually indicates the feeling of a people treated as though they are NOT welcomed here.
