I didn't know Africa was the largest continent until the 7th grade (around 84-85). We had an assembly and the speaker was on some educational shits and showing us slides of shit when she came across a slide of the map showing Africa to be this gargantuan land mass. She then proceeded to tell us that, in fact, Africa was the largest of the continents and the reason we were always shown a map that showed it smaller was because of some old world racist euro-centric white supremacist shit... And this was a white woman telling us this.
That weekend I tried to school my militant stepfather on it and he pulls out a map we used to have on the wall and he was like "... son... you should have ALWAYS known that. "
