Which term describes a person who favors extreme political change?

The term that describes a person who favors extreme political change is "Radical." Radicals seek significant alterations to the existing political, social, or economic structures, often advocating for transformative ideas that challenge the status quo. They may push for revolutionary changes rather than gradual reforms, reflecting their desire for a substantial departure from current policies or systems.

In contrast, reactionaries aim to return society to a previous state, conservatives prefer to maintain traditional values and slow evolution of change, and moderates advocate for a balanced approach that often incorporates elements from both ends of the political spectrum. Therefore, the understanding of "Radical" is crucial for grasping the broader spectrum of political ideologies and movements.
