I would say that yes wicca does revolve somewhat around "gothics" a lot more. Wicca being an unrecongnized religion for so long is not the average religion that can be accepted by just anybody and everybody. In actuality wicca is usually put into the same context as witch craft and black magic due to the inacuracy of the people who publish it. I would say that gothics are drawn to it becuase it is an extrodinary religion that has just recently been shed light on and it is because of this taboo that surrounds it that gothics are drawn into it. You cant say that in reality it revolves around them, but I can say that it has been more publicized/famed becuase of the gothic crowd.
