Listen, music has a huge influence on life...just as life has a huge influence on music. Like moths to a flame, people with be attracted to whatever group best fits their needs. People in gangs are craving acceptance on many levels, also they need that 'family' to fill their needs. Many kids in gangs are from really bad families, parents in jail, on drugs, kids left alone to fend for themselves. No nurturing, no involvement from the parents...You need to look up Sigmund Freud and his theories on the ID, the Ego, and The Super Ego, his theories elaborate on the theory of Inner Desires. Look this up and you will understand.
