Lets think of a few:
Working with animal remains
Taking and sharing photos of altars
Okay right off the first five are historical, long held, deeply entrenched parts of traditional witchcraft practices. How can a practice be trendy, if it appears repeatedly in the medeival witch trials? With the advent of sanitized public writing about Wicca, many of the roots of witchcraft were erased. Their return to their rightful place in witchcraft is not a trend, its a revival, and a long needed one at that. It started with a few non-wiccan traditions putting out books about their practices. With the death of Andrew Chumbley, and the sky rocketting in resale prices for his previously barely heard of books, attention turned the bootlegs and in short order more and more books were being put out on traditional witchcraft. Bolstered by Ronald Hutton’s Triumph of the Moon authenticating both Andrew Chumbley and Victor Anderson’s old craft roots, and more recently Sabina Magliocco authenticating Raven Grimassi’s folk magic heritage, traditional witchcraft has popped out of the earlier (but recently disproven see Phillip Heselton’s books) shadow on the legitimacy of Wicca into the bright moonlight. As a result there is a great increase in the number of books coming out of Britian and making their way into America (Out of publishing houses like Xoanan, Three Hands Press, Mercurial Press, Troy Books, Scarlet Imprint and Cappall Bann, for example) as well as a few American writers putting out some valuable material (Raven Grimassi, Grayson Magnus, Victor and Cora Anderson) and even a few Austrailans (Lee Morgan). Its just hitting the point now where a curious reader is faced with too many choices and needs help to figure out what is derivative “dark fluff” and what is the source material.
Add to that the renaissance of ideas and sharing on Tumblr (before that livejournal), Facebook, and earlier and so valuable forums as yahoo groups, and the traditionalwitch.net and the now defunct traditionalwitchcraft.net sites. We even have a handful of online schools and dozens of great blogs like Sarah Lawless and Nicholas Frigvold and we have a vital growing set of cults rather than “trends”. Sure in any realm one has folks who are looking but haven’t found home. You see them drop off after a year and go onto the next thing looking for where they belong. Often these being the most excited and elaborate sharers, telling us of very detailed otherworld journeys that read like movie scripts. But some of those stay and settle down a bit as they learn fantasy from spirituality. It does no help to just call it trendiness, it helps the most to provide your own more centered content as a beacon, and let everything fall into place. The hardest part is for other new folks who aren’t getting the fantasy level and worry that they aren’t spiritual. Those of us further along the road just need to reach out to them. Bloggers who write about otherworldly travel in detail and then all but forbid their followers from attempting it do nothing but confuse. Be honest, its not a trend—its a big part of witchcraft traditions, nor is it something everyone who experiences it is prepared to guide or teach others on. Perhaps it is more reasonable to stop yourself from bemoaning the trendiness and instead admit, hey I write about this stuff, but I am not able to teach you about it, please keep looking, there are teachers out there.
Now for the last. I keep hearing folks say that oh I would never take a photo of my altar, and they too bemoan the trendiness of it. Look some people are inspired to share their ways with others, provide a point of reference. Gemma Gary and Doreen Valiente for example. Others feel more private but draw and paint altar set ups. You are not required too, but those who do blog and show their altars follow a long tradition across many spiritualities of doing so. It is not a trend if its been going on since its been legal to write about witchcraft and printing photos has been cost effective. Its a reality—some witches are called to share photos.
