The Crusade's

As I read about the crusade's I shudder. I have a hard time imagining what it must have been like for anyone in those times. Fearful to say the very least. It makes me sad to know that a faith that teaches love and tolerance had such a violent and aggressive beginning. Thousand of years later we are still fighting a war over peoples right to warship freely and not to impose one religious doctrine over another. Will humankind ever learn to live in peace?
