Real life,
Yes, ideas and misuse are separate things, but when ideas lead to wide, not just extremist, misuse, surely that says something about the ideas?
You say that America is tolerant. Have you not read the title of this thread? It is in America that the KKK are rising for a second time, not only condemning blacks as soulless animals, but now attack imigrants as well? In no other society do you see as much racism. And I think I know what it is due to.
Do you know that people used the Bible to justify slavery? Obviously not. People said that blacks were the descendands of Ham, whom God had condemned.
Also, slavery is ripe in the Bible. It's everywhere, and God does nothing to stop it, or even show any sign of objecting to it! In fact, slavery is used as a background part of more than one parable. The Bible = Freedom and Tolerance? Yeah right.
Did you also know that slavery exists in America? Africa, I can handle - they're up to their knees in sh!t, but America? The enlightened people? The greatest society on Earth?
Christians?? Here is a the first of 211,000 results I found when typing "slavery in modern america" into Google.
You should try reading the Bible sometimes, real life. It will fill in a gaping hole in your education.
