Let me ask you this first, Dave, before we launch into a useless discussion. If I show you facts that demonstrate that there was ethnic violence, even slavery in Africa, Asia and the Americas long before the White people showed up, would you change your mind?
Are facts even important to you on this topic.
The argument that I am making is that the White race is not inherently evil. Humans of any race have the capacity for great good as well as the capacity for great evil. This has been demonstrated throughout history.
Just so you understand... I am not arguing that Slavery, or Colonization or any of the other injustices perpetrated on Africa and America by White Europeans was justified in any way. Slavery and Genocide are immoral and unjustifiable.
The evil done by the European colonizing power was due to human greed and violence (which have been demonstrated by all human races) combined with the fact that they alone had the technological and economic power that gave them the ability to subjugate more people than every before.
But you see the same level of greed, violence and injustice throughout history when one society gets more power than its neighbors. Examples include the Nubians (of pre-Colonial Africa), the Aztecs (of pre-colonial South America) to the enemies of the Anasazi (who were wiped out in pre-colonial North America) to ethnic groups driven from pro-colonial India).
By the way, I am really surprised you brought up China... a country that has suffered centuries upon centuries of ethnic conflict.
None of these had anything to do with White people.
