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.
Arguing with someone on an online forum is very rarely going to set that individual on the right path, but I like to believe others who read the back and forth may be more persuaded. I often take initiative to explore a topic I knew little about beforehand because someone asserted something I found surprising or simply suspicious. If people go as far as to post references, it's even less of a burden on me to learn something new.
I'm more like this on Facebook. Lemmy being a bit more ""technical"" I feel like thats less of a thing, that if a Lemmy user was going to read about something they probably already did. I could be wrong but eh.
