Indeed. The only way to rectify the errors that got us here is by sharing information and spreading awareness of what was changed/lost...and I don't think being hostile towards the people who are taking an interest in a topic over their cultural history really helps that along...

Well that's the problem isn't it? If the knowledge exists but it isn't as widespread as anything else, it is much more likely to become the accepted "discovery point" of something.

While I think its rather unlikely for the idea of Belgians being the inventors of chocolate becoming widely accepted as fact by the people who matter when ruling on discoveries, it isn't that much of a stretch to see why it's "whites" who are listed as the discoverers of things since they're the ones who had the power to make it a reality.

I'm not advocating for the stance that "well, the Europeans won so they should get to be listed as discoverers of things," but on a certain level that is the unfortunate reality of the situation for many things: Europeans conquered and smashed their way (whether on purpose or accidentally) into being listed as the discoverers of many things. If the records of X thing existing didn't exist until the Europeans cataloged (stole) it, there isn't much to be done in changing that reality without concerted efforts by people to change that.

Overall, I think we've taken a lot of steps in rectifying that situation, but its a difficult process to complete, especially when it comes to oral histories.

I will also note that the hostility isn't really productive. I don't think anyone who is interested in this topic is terribly likely to have some hatred of the natives who were likely aware of things before Europeans, so to immediately act with hostility only really serves to hurt the cause of spreading awareness about the discoveries of indigenous people.
