that happened in africa and every country where people where not white,
It is not that evolution itself is to blame, but it is the way people have used evolution to view non-white people as being of an inferior race lower down on the evolutionary scale. One prominent evolutionist stated that the intelligence level of black Africans is equivalent to a European 11 year old. This is just human prejudice hanging it on the available evolution nail.
So, for Christians, instead of aiming our gospel cannons at abortion, homosexuality, rape, racisim, and all the other evils that are built on the foundation of evolution, we should aiming our big guns at the foundation instead. This is what evolutionists are doing, they are firing their big guns at the foundation of our Christianity and this is causing the building on top to shake and start to crumble.
If a person is evolutionist, then there is no set rules for them, and that anything goes, including abortion, homosexuality, pornography, and lawlessness. Meaning of life, standards, marriage, and laws go out the window. That is why a woman can have her unborn child murdered and have no conscience about it, because there are no set standards on which to base her view of right and wrong, because on the foundation of evolution there is no right or wrong.
A good question to ask an evolutionist is, "Can I shoot you?" If he says that is wrong, we can say, "There are no rules, we can do what we like can't we? And if I think you are an inferior species of human, I can purify the race by killing you off, can't I? That's what Adolf Hitler did, and he thought he was a good person doing the best for Germany!"
