This is racist tbh. How can you not be back enough?
How can one not be black enough? Very simple. Thanks to colonialism and the one drop rule there are black people all over the new world (North America, Latin America, and the Caribbean) with varying degrees of African blood. Some are more mixed like Zoe Saldana and others look like Nina Simone with many others in between. Long story short even to this day the lighter ones or the ones that are less African looking are favored. To this day think about all the famous black celebs that many find attractive and desirable.
You're from Buenos Aires I'm sure you know all about this.
In what nation?
