However, many centuries later, this does not "excuse" the re-emergence of such behavior. I know the current persecution didn't begin overnight. "Re-Emergence" may not be the best choice of words. It has been increasing as the Christians increase in number and expand into Muslim-dominated terrtories.
But as most of us have gotten over the Civil War of the US in that northerners and southerners can co-mingle somewhat peacefully 150 years later, the civil war between the Arian Christians and the Muslims should have died out a very long time ago.
I do realize that battles fought on religious premises do not just suddenly die out, however. I guess it's just wishful thinking that the "My God is better than your God" syndrome would just go away.
Thank-you for your thoughtful and informative response.
Actually for more than 50 years Christians have decreased in number relative to Moslems, and have been withdrawing from Muslim-dominated territories during that period. And the conflict (in the terms I suggest) is between the main-stream Christians, and the Arian-descended Moslems not between the Arian Christians and the Muslims.
