I've hung out with many New Agers over the years and they would describe themselves as having no religion, with a handful of exceptions. It's mainstream stuff -check out the magazine racks in Smiths and you'll find Spirit and Destiny, Kindred Spirit, Soul and Spirit, Prediction - the book section will have at least a coup,e of shelves of books on Angels, manifesting and the LoA, past lives, psychic experiences, tarot, astrology etc etc. I don't think it something we need to get fussed about - I've yet to meet an angel 'expert' who expects a seat in the House of Lords.
Quite what it will mean for this country when Islam is the majority organised religion - which it surely will be eventually - is anybody's guess.
