For context, the post I'm referring to is a map of Africa with subsaharia Africa in deep green, Sudan in light green and north Africa was white or some other color. The poster was claiming nothing had ever been invented in the green zone. My comment was gonna be this:
Antiseptics before Europeans.
Iron Smelting Not the first to discover it, but recent evidence show it was invented independently.
Some modern Archtecture taking inspiration from Sudano-Sahelian features such as a roof shape favoring natural ventilation. And since I just transitioned to recent inventions, there's the Cardio Pad, invented in Cameroon, to help diagnose cardiovascular disease.
I get where you're coming from. I really do.
That kind of racism can't be reasoned with. All the proof you have, they've seen, and are looking for a flight to refute it. It's far easier for them to lie than it is for you to prove them wrong.
Simple deleting it is the best possible outcome. Responding to them just gives them an additional platform.
