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.
Thanks for the clarification. It seems I suffered from a case of dyslexia in that I confused the origins of each side.
I appreciate the information.
