Here's why:
* Subculture: A subculture is a group of people within a larger culture who share a distinct set of beliefs, values, and practices that differentiate them from the dominant culture. They often have their own unique language, fashion, music, and rituals.
* Counterculture: While similar to subculture, counterculture is a more radical term. It describes a group that actively opposes and rejects the dominant culture's values and practices.
* Culture: This term is too broad and refers to the shared customs, arts, social institutions, and achievements of a particular nation, people, or group.
Therefore, subculture is the most accurate term to describe the formation of a new cultural group away from the rest of society.
