If you don't take it at face value, your risk making serious judgements on people, which is not the point of statistics.Well i guess if you take at face value what people report during a census and what governments report.
To be honest, every religion has a large percentage of people that aren't really what they claim to be. Wicca is no exception. The difference being is that Wicca isn't defined by its beliefs so much as it is by its ritual practices. It doesn't matter what someone believes or claims, if they don't follow the traditional practices, they aren't Wiccan.
Now, decades ago, this would be a huge stumbling block; Wicca had always been an initiatory, oathbound, coven-based fertility cult. But since the late 1970's, a lot of information about Wicca's practices have become public information.
History would definitely disagree with you there. Buddhism is well established in many East Asian countries and societies as a religion, with all the ecclesiastic accoutrements associated with organised religion.Buddhism could best be called a philosophy rather than a religion
In any case, religion itself is merely philosophy with action; religion is normally defined as thinking a certain way, and acting a certain way based on that manner of thought. The way of thinking is philosophy; the way of acting in the practices associated with that ideology.
