Fanaticism is an emotion of being filled with excessive, uncritical zeal, particularly for an extreme religious or political cause, or with an obsessive enthusiasm for a pastime or hobby.
According to philosopher George Santayana, "Fanaticism consists in redoubling your effort when you have forgotten your aim"; according to Winston Churchill, "A fanatic is one who can't change his mind and won't change the subject".
The difference between a fan and a fanatic is that while both have an overwhelming liking or interest in a given subject, behaviour of a fanatic will be viewed as violating prevailing social norms, while that of a fan will not violate those norms (although is usually considered unusual).
A fanatic differs from a crank in that the latter term is typically associated with a position or opinion which is so far from the norm as to appear ludicrous and/or provably wrong, while the subject of the fanatic's obsession may well be "normal", with only the scale of involvement being abnormally disproportionate.
I had a recent experience with a fanatical LDS member. It is the first time I have personally discussed Mormonism with somebody who believes in ALL the teachings of the Prophets, including racism, polygamy required for exaltation, Adam God, blood atonement, etc.
It is more disturbing than anything I have come across in apologetics, but it was the first time to discuss LDS doctrine with a member who actually understands the Mormon gospel they have embraced. I was amazed and sickened at the same time. Apologists on MAD seem like a comfort all of a sudden.
As a fanatical member, she professed to do ANYTHING the Prophet commands, and believes all the Prophets teachings are from the Lord. All policy, changes in policy, changes to ordinances, white washing of history, interviews, etc. are all from the Lord to this person. She has never been in the world of apologetics, never been on the internet, but suprising to me, knew all of the troubling history and embrace it as God's command. The Prophets are not perfect to her, but their teachings are. Through the spirit, visions, etc. she KNOWS these doctrines and all teachings in the Journal of Discourses are true and would give her life for them. When I suggested that many of them were "opinion" now and the only LDS doctrine is canon according to apologists, she spoke with such force and conviction that none of those teachings were opinion.
Things that are not recorded in the scriptures she has seen through the spirit. Ex: although there is no recorded polygamist Prophet in the Book of Mormon, she KNOWS that they practiced it & the Lord left it out for a reason. Also, in the Bible, there is no indication the polygamy was ever required for exaltation, but she believes it's there if I let the spirit speak to me. God having sex with Mary? "sacred and true."
Jesus and God as polygamists? The spirit confirms it to her.
All I can say is that I am very freaked out and traumatized by the discussion we had. She claimed to have felt the spirit the whole discussion, yet I felt a dark scared feeling. I had no idea this person held these beliefs. She seemed like a typical LDS member all the years I have know her. What amazed me was her lack of any research on any of these topics, but "the spirit" taught her these doctrines. Her knowledge of history was unbelievable for a person who doesn't read anything but scriptures and church approved materials.
I am in a difficult position now. This is a relative, and one I have been close to. I am very troubled by what this person shared with me and feel very uncomfortable to be around her now. Many things were said to me that were offensive and cruel. (about my inactivity and struggle with doctrine.) Most of the discussion revolved around her analyzing every part of my testimony, all of my experiences, my personality, etc. so she could figure out why I haven't felt the spirit speak to me of the truth of these teachings. One of the most hurtful things said to me was that it's my fault I didn't know that plural marriage was a part of the plan for exaltation before I took out temple covenants. She couldn't believe I would make covenants without understanding the doctrines of the church. I was chastised for it. I was also given indirect statements that my DH would have a right to divorce me for my beliefs now. (keep in mind I am not an apostate yet, just open minded about the possiblity that the church is false and disillusioned with it all) She is unable to see that my marriage could survive this, or the love for my children could be the same now with out the LDS gospel. In other words, this is spiritual infedility to her and most of the family, so shame on me for struggling and going inactive!
Have any of you had to deal with this situation in a family or with friends when the person is a fanatic? I am unsure of how to handle this as I try to repair our relationship and defend myself.
It's been a very painful week for me since this occured and unlike anything I have had to deal with yet.
