I guess being sort of a peace lovin' gal I guess my thoughts are that since I think nearly everybody's "right," then it would follow that their rituals or practices would also have power regardless of my own belief or practice.
I visited a local shop that markets to witches and wiccans, with lovely soaps, incense, candles and books etc. and in just examining some of the ritual objects (cauldrons, candle holders, and the like) and thinking about their uses I was impressed with the level of power I sensed they could evoke with the right handling and belief. Not MY power, just a sense of somebody else's, if that makes any sense at all. Like not being Catholic and visiting a shrine or a cathedral and getting a sense of people worshiping there in a faith and ritual that doesn't belong to you, but is real to them.
