Unlike most of the writers covering the Duggar sex scandal, I was raised in Advanced Training Institute (ATI), the fundamentalist Christian organization with which the family is affiliated. Joshua Duggar’s confession of sexually molesting young girls in his family’s home when he was a teenager didn’t surprise me, nor should it surprise anyone with any intimate knowledge about this organization, because ATI’s theological beliefs and practices cultivate an environment where women and children are more vulnerable to rape and sexual abuse. Ironically, the same theological beliefs and practices at the heart of this scandal are the same beliefs that created the Duggars as a media phenomenon, and drew viewers and fans to their TLC show “19 Kids and Counting.”

Non-mainstream religious sects have certainly been enjoying a cultural moment on television: “The Following,” “Sister Wives,” “Breaking Amish.” Netflix’s dark comedy “The Unbreakable Kimmy Schmidt” explores the media hype around religious cult survivors in satirical detail. For me, though, that show should have come with a trigger warning, because in many ways, I am a real Kimmy Schmidt — a woman who spent her adolescence trapped inside a metaphorical bunker, and then was thrust into a world that she had never been prepared to be a part of.

The Duggars didn’t emerge from a subterranean bunker, though. They’ve been on TV promoting the fundamentalist Christian theology of ATI since their first special in 2004 (“14 Children and Pregnant Again!”). ATI is a Christian homeschool organization that hosts seminars worldwide, provides homeschooling curriculum, and even runs its own paramilitary training center. At one point, it was strongly affiliated with a Christian correspondence course law school. Its members are not concentrated in one area, and yet they maintain insular groups and often form churches in which all members are affiliated with ATI and/or follow its basic principles. Referred to as “Gothardism” within fundamentalist Christian circles, the teachings of ATI form an ideological system of practices based on the extremely strict, fundamentalist, and idiosyncratic Biblical interpretations of the organization’s founder, Bill Gothard – a man who, in 2014, stepped down as head of ATI following allegations of sexual misconduct with young girls.

The allegations against “Mr. Gothard” (as he is respectfully and worshipfully referred to by his acolytes) were an open secret among group members for many years. As a friend who worked at ATI headquarters once said to me with a wink: “The prettiest girls are always chosen to work the closest with Mr Gothard.”

ATI’s teachings trickle down into every single part of its members’ lives. This is not just a homeschool curriculum, it is a fully institutionalized religious sect with incredibly strict demands to conformity — rules that, in my experience, more often reflect Gothard’s personal preferences than actual Biblical teachings. Have you ever wondered why every Duggar woman perms her hair? It’s because Gothard taught us that curly hair brings out a woman’s natural beauty. Other ATI beliefs that I learned range from utterly bizarre to downright barbaric, like the creator of Cabbage Patch Kid dolls is actually a Satanic wizard who implants demons into the dolls that then sneak into children’s bodies while they are sleeping — along with the old standard that rock music is inherently sinful. One boy from our church would walk around supermarkets with his fingers plugged into his ears to prevent himself from hearing it.

And then there are the beliefs that are more central to the portrayal of ATI on TV through the Duggar family, which are also shared throughout the church’s teachings: the antiquated dress codes (especially for girls and women), the required homeschooling, the prohibition on birth control, the strictly gendered division of labor and the absolute and unquestioned authority of the father within the home.

One key difference worth noting between the “reality” show of “19 Kids and Counting” and the actual reality of ATI, though, is the relative affluence of the Duggars compared to most ATI families. The Duggars live in a spacious Discovery Networks-funded home, but it was not unusual, in my church, for two parents and ten children to live packed into a singlewide trailer. These children usually wear threadbare hand-me-downs already passed through several rounds of siblings. Many of them look malnourished due to the abundance of starchy meals necessary on a lean one-parent income. Women and mothers working outside of the home is absolutely forbidden in ATI no matter what the financial situation of the family. Some women are even required to get permission from their husbands if they want to obtain a driver’s license.
