What term describes the beliefs and actions of individuals who support radical ideological, religious, or political views?

The term that best describes the beliefs and actions of individuals who support radical ideological, religious, or political views is extremism. Extremism refers to the adoption of extreme views that often deviate significantly from the societal norms and can lead to advocating for or engaging in actions that are considered outside the bounds of accepted practice or law. This can manifest in various forms, whether violent or non-violent, but it fundamentally involves a deep commitment to radical beliefs that are often at odds with the prevailing values of society.

Radicalization refers to the process through which individuals adopt extremist views, but it does not encapsulate the ongoing beliefs and actions that these individuals might hold once they have become radicalized. Terrorism, while often linked to extremism, specifically refers to acts of violence committed to intimidate or coerce for political, ideological, or religious purposes. Mobilization typically refers to the process of rallying support for a cause but does not inherently refer to the extremist ideologies themselves. Thus, extremism most accurately captures the essence of individuals who support radical views.
