Africa is continent of 1.1 billion people — roughly 16% of the world’s population — and 54 countries. Still, it is not uncommon to hear it referred to as a country, often out of ignorance or even as an insult.

Well, one of the biggest stars to come out of the continent made clear that this isn’t acceptable. Lupita Nyong’o, who was raised in the East African country of Kenya before attending college in the United States, posted the following meme to her Instagram account.

Much of Nyong’o’s family still resides in Kenya. Her father is a Kenyan Senator and her mother is director of the Africa Cancer Foundation.
