This is Wikipedia's page for "List of the occult secret societies" as of right now:
As you can see, the relevant text is, "This page is a partially complete list of the occult secret societies that have received coverage in a few sources due to allegedly being secretive in nature and also allegedly being interested in the occult."
And then, the LIST IS EMPTY. That's how Secret they are!!
Mostly it ended up this way due to a vibrant deletion debate. The page was created on January 23, 2010 by editor "Denso 90 vn", who included these groups in the list: Templars, Rosicrucianist, Masons, Hospitaller, Teutonic Knights, and Golden Dawn. The content was improved slowly, and the article was nominated for deletion on February 7. Then, as the deletion discussion progressed, the list was whittled down by various editors, until the very last alleged occult alleged secret society still on the list, Skull & Bones, was removed. It should be noted, however, that on October 19, 2004, a letter writer to the Ellensburg, NY Daily Record revealed that "both George Bush and John Kerry are members of the occult secret society, Skull & Bones."
