Goth, although once an expression of individuality, is now a commercial image sold by big business. They now have shops such as Emily the Strange that promote and sell the goth image. If you shop at such places you are buying something that everyone can have and probably does have. Ergo, you are not a true goth who wishes to be individual.
Goth, as well as many other social groups, is a box that people are put in so we can organise society. People are labelled to make it easier for others to relate to them. I exhibit many chracteristics of a goth (outlook of the world, sense of humour ect,) but am I one? No. This is because I choose not to buy into a commercial image that has been ruined by our "friends" big business and lemming teenagers.
So, if we follow this philosiphy, everyone who calls themself a goth is a poser and everyone who dresses like a goth is just buying into a commercial entity and is therefore a sellout and a poser.
Goth: I'm so individual I dress and act just like all my friends because society tells me to.
