The document discusses how culture and identity are constructed. It defines culture and subculture, noting that subcultures can form based on age, gender, sexuality, or religion. It then explains that post-modern sociologists believe identity is not fixed, but can be constructed from a variety of sources, similar to a pick-and-mix counter. In particular, the media plays a key role in influencing and helping construct identities, as seen through various youth subcultures that formed in the 1980s based on shared music tastes, dress, and self-identification. The document ends by asking the reader to reflect on how they construct their own identity and how the media has influenced them.
