When will the positives of african history be put into the history books?

Don't you get pissed when you open a history book and all you see is people getting lynched or burned and the negatives like emmit till. The 4 little girls being church bombed rosewood and everything else. Why can't we learn about warriors and kingdoms of africa. Like the Mali empire, Songhai, Ghana, Zulu, Sundiata, Queen Nzinga warriors the Warriors of Nubia Like Kandake who defeated the romans in battle or queen nanny of the maroons of jamaica. Ive already learned about the man who has 1,000 ways to use a peanut or runaway slaves. That isn't the only thing I want to learn. Oppose this era of making us look like we weren't fierce noble people. We are the noble and the proud and our legacy will stand forever. Notice I didn't mention egypt I don't have to look at the pic in my avatar box. That is seti and he was not one of the nubian rulers of egypt
