Wanna be a real punk? quit spending mommy's money, get a job, and get involved in the world around you. Vote, research politics, plant a tree, volunteer at a soup kitchen, and support local musichians, venues, and record shops. Hell, you can even take part in a protest rally if you think that will accomplish anything. Write to your cogressman. (or woman.) But don't sit on your passive ass and bitch. Stand up and do something.
Don't do what every one else does just to be trendy, but don't rebel just to scare your parents or church or whatever. There is no such thing as a rebel without a cuase, just a rebel without a clue. To quote Joey Comeau
