Sectarianism fails to see the humanity of other people

We can debate sectarianism and why such narrow-mindedness still afflicts societies, but it is axiomatic that hating another person because of their religion is wrong.

The term ‘narrow-mindedness’ is appropriate, because those who espouse sectarianism have such a restricted view of the people they hate.

They see nothing but their religion and nothing in the religion except aspects they loathe.
