Actually, you are correct. It is about finding beauty in what others consider dark. The rich silence of a moon lit night in a cemetery. The shadows that dance on a dark country road. The beautiful sheen of a raven's feather. The pure whiteness of a skeletal bone, echoes of a life once lived. Styles of an era long passed by. The mournful solitude of the grave.
The solemn, rich dignity of the true goth has been lost and buried by American traditions, misunderstanding, and misinterpretations. Having satanic items does not make you a goth. Dressing up like the Crow does not make you a goth. Wearing black and being moody does not make you a goth. (That is actually emo by the way.) Performing blood rituals does not make you a goth. Casting spells doesn't make you a goth. Just because you like to wear dark colors does not make you a goth. Terrorizing people and being rude while running around with your face painted, dressed in black does not make you a goth. It makes you a bully, but not a goth.
Being goth is not a choice. It is who you are at the very core of your being. You don't have to choose to behave this way. It is merely who you are and you should never apologize for being you.
