sectarianism
A sectarian conflict usually refers to violent conflict along religious and political lines such as the conflicts between Catholics and Protestants in Northern Ireland (although political beliefs and class-divisions played major roles as well). It may also refer to general philosophical, political or armed conflict between different schools of thought such as that between Shia and Sunni Muslims. Non-sectarians espouse that free association and tolerance of different beliefs are the cornerstone to successful peaceful human interaction. They espouse political and religious pluralism.
