I think our communities adoption of white issues, practices, Western vices and silliness is what led to our downfall.
To be honest, even with technological innovation, African hundreds of years ago was about a gazillion times better than it is today.
Whites were a disease that infected that continent. Adoption of their policies fukked up gender roles, stole land from women which led to famine, pollution, exploitation, abuse, death, torture, enslavement, loss of knowledge, loss of history, spread of false stereotypes about blks that are still entrenched in the world today...thanks but no thanks. The white way ain't it.
