Mystic Rainbow, Wicca is common in the US but did not attract wide popularity in the UK because Traditional Witchcraft is still strong here and wicca is seen as somewhat trivial. Having said that, many of us started off in wicca but soon departed to deeper levels.
In my area, we celebrate the old pagan festivals at a 5000 year-old henge which attracts large crowds but few overt wiccans.
You are what you are and do not need to justify yourself. If anyone presses, just reply "Pagan" !
