Personally? No, but I am not a Wiccan or really any of the 'mainstream' pagans, nor do I practice witchcraft. I'm a chaos magician who practices chaos magick, a manipulation of the astral with the understanding that the fundamental principle behind both our own realm and the astral realms are grounded in primordial, beautiful chaos. To me, chaos magick is different from witchcraft: there is a much heavier influence of ceremonial magick and candle magick, and less of herbal or stone work. There can be debate on this, of course, but since the ideology behind the two practices is different, the two should not be equated.
In general, I don't necessarily equate the concept "witchcraft" with the concept "religion", because I see witchcraft as being a part of the whole. Religion, after all, encompasses many differnet constructs, among them views of the afterlife, concepts of divinity, ethical and moral systems, etc. Witchcraft by definition does not do any of these things, but rather is a practice, a way in which to live religion. Witchcraft is certainly a part of some religions, but should not be directly equated with the religion as a whole.
