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.
It used to be difficult, I feel like it's easier these days to tell that someone is sealioning. If someone is so invested they're angry about it they're probably just trying to waste your time. If somebody is just like "Oh I've never heard of that, where'd you see that?" then I might link something.
That's another thing I hate that I don't put up with anymore that's kind of related, people who are all snotty and shit but when you snark back they're like "AHHHHHHH GOTCHA NOT VERY TOLERANT OF YOU" (or whatever) Whatever dude lol
Tolerance is a social contract that doesn't extend to assholes. They think it is a cheat code that everyone has to calmly listen to their vile bullshit.
