True. But if you zoom further out, it becomes genocides again. The rise of humans was only possible for the downfall of other species. The rise of human civilization spelled doom for many others.
Ok, genocide strictly only applies to other humans. Anyways the core idea remains: For one culture to spread, others have to give way.
No one notices someone that does small acts of kindness.
Sad, isn’t it? History books are like a gallery of psychopaths grabbing for more and more power.
