Oh!

Some Caribbean tribes routinely made raids on their enemies, such as the Tainos, capturing them butchering and devouring them, and enslaving and raping their women. Young girls were captured and raped to produce infant children, whom these demonic scumbags regarded as especially tasty and tender.

Zulu tribes in Africa were constantly at war and would burn down entire villages, slaughtering men women and children indiscriminately and roasting alive in cannibal feasts. They enslaved each other and/or sold their fellow Zulus to European or Muslim slave-traders with no remorse.

Asian Indians would burn widows alive so they could join their husbands in the afterlife.

These people were called savages for a reason. They did savage, inhuman things to each other. They were locked in an eternal dark age, developing no technology that could even distantly compete with Europeans. They were culurally inferior in every conceivable way, from art to philosophy to mathematics to science to technology to morality.

Do not uphold these cultures as examples to be emulated. These are illustrations of the depravity of human nature and cautionary tales of what happens in a world without Christian ethics.
