Do you actually know anything about history at all? Do you understand where segregation started, and what the predominant religion is in that part of the world?
There has been slavery and segregation in one form or another all over the world, so that the Bible is full of mention of it. The Israelites were even supposed to segregate themselves. What exactly are you referring to, then?
And I am talking about the U.S. right now, in the world we live in today.
