Are Christians Racist?

I ask this question because of a post I read the other day. A little girl ask her mother if that couple (the lady was white and the man black) was married and if that was wrong. The mother then ask the little girl does me and daddy have the same color hair? The child said "No". The mother ask do we have the same color eyes. The child said "No" again. The mother said are we the same height, the same weight, etc... The child's answer was always "No". The mother then said that God created Man and Women. He didn't create a White Man and a White Women. And that the color of one's skin is just like the many other differences in our appearence. The women ask they child why she thought it was wrong but the little girl couldn't say why. The women blames society and living in the South.

After reading this post it got me to wondering. I have always heard from one person in particular, who I go to with question about the bible and he has always said that the bible says marriage of a different skin color was wrong. So, I did some digging into the bible. This is what I have found.

Numbers 12:1-16. It tells how Moses was married to an Ethiopian women and how Miriam and Aaron spake against Moses. The Lord became angry with Aaron and Miriam for speaking against Moses. He then made Miriam White with Leprous. Moses pleaded with the Lord and eventually she was let back into the group.

There are other passages in the bible that says that the Lords children shouldn't marry a particular group of people but it doesn't say because of the skin color. It says that they will turn your sons against the Lord and towards their Gods. He also says that we shouldn't marry others who are not Christians, but still nothing about different color skin.

So, far I have found no passage in the bible saying anything against marriage or dating of someone of a different color than yourself. So, this gets me to wondering if Christians have become racist because the world sees marriages of different colors as wrong? Even if the bible doesn't say it is wrong to do so anyone who does will have to deal with a harsh life. With the looks from others who believe it to be wrong and sinful.
