Intolerance

Intolerance is the lack of ability or willingness to tolerate something.

In a medical sense, intolerance refers to the inability to ingest medications or foodstuffs without harmful allergic (or other) reactions.

In a social or political sense, it is the absence of tolerance toward others of differing viewpoints. As a social construct, it is very much open to subjective interpretation.

Common forms of intolerance include racism, sexism, homophobia, and religious intolerance.
