Final answer:
A counterculture, such as the Ku Klux Klan, rejects societys norms and creates its own rules, existing in stark contrast to the mainstream. Subcultures maintain unique traditions yet coexist within the larger society more harmoniously.
Step-by-step explanation:
A group whose norms and values are incompatible with the dominant culture is called a Counterculture. A counterculture explicitly rejects and opposes the norms, values, or laws of the broader society, endeavoring to live by alternative principles that may be at odds with mainstream culture. For instance, the Ku Klux Klan is an example of a counterculture because of its stark opposition to societal values of equality and respect for diversity.
Conversely, a Subculture is part of the larger society but maintains a unique set of traditions, beliefs, and values within a smaller group. Subcultures coexist more harmoniously within the larger society compared to countercultures, which are actively 'against' the dominant ruling culture and seek to establish their own values, often through radical change.
