Cardi B thinks the US school system is to blame for the ignorance surrounding "race, ethnicity and nationality".
The chart-topping rap star - who is the daughter of a Dominican father and Afro-Trinidadian mother - has taken to Twitter to hit out at "uncultured swines", but also insisted they're not to blame for their own ignorance.
Alongside a video discussing the Dominican population, Cardi wrote: "For the uncultured swines that don’t understand the difference between race, ethnicity and nationality especially when it’s about Caribbean islands. I don’t blame you tho. I blame the school systems (sic)"
In the video, the narrator explains: "The Dominicans are one of the most diverse ethnic groups in the world, with around 73 percent of its population identifying as mixed. Historically, it was the first permanent settlement of the Spanish in the Americas and the first place to transport African slaves into the New World."
Earlier this year, Cardi bemoaned the "one-sided" history lessons taught in US schools.
