When I read a question like this, I wonder about the definition of the word "cult". I wonder if we're all working on the same definition.
By my definition: no.
But, my definition includes isolation from family and friends and adult brainwashing, maybe even some threats. Definitely some element of control of members. The church I grew up in called Jehovah's Witnesses and Mormons cults. True story: the Jehovah's Witnesses built a "church" or whatever they call them straight across the street from my house when I was in junior high (before we moved out into the country). This earned me a lot of uncomfortable extra attention from my own church. At the time, I figured they were worried about competition. I don't consider either of these cults.
After we moved into the country, my new town had a huge Freemasons building. We had our prom and our graduation in that building. I don't have a photo of my own. This photo is not how I would have composed it because it doesn't show the scale of the building. But it was HUGE.
Now, I left the town at age 22. However, what struck me back then was how old all the people were. I know I have read that freemasons are dying out, though I was too lazy to look up the source for this post.
Frankly, I think most of the mysticism surrounding them is either historical or because of lingering secrecy that allows imagination to grow.
