What does sectarianism mean?
Sectarianism is the practice or doctrine of treating one religious, political, or social group as distinct from and often superior to other groups. It commonly refers to divisions based on religion, ethnicity, ideology, or factional loyalty, particularly when those differences lead to hostility or the belief that people outside one’s group are untrustworthy. The word is more formal and generally carries a negative connotation. In contemporary usage, it often appears with terms such as “religious,” “violence,” “tensions,” and “conflict.” Historically, sectarianism referred especially to divisions and rivalries among religious sects. Understanding the word involves recognizing the distinction between ordinary group loyalty and a more rigid pattern of separation, distrust, and hostility toward other communities.
The doctrine or practice of favoring one religious, political, or social group over others and regarding the groups as fundamentally separate.

Sectarianism turns belonging into a test of loyalty: the difference between sharing a community and treating other communities as rivals.
