Ok sorry for taking so long to reply, been a crazy week.I'm not familiar with the movement; what was it that led to such things?
ATI from my understanding taught biblical headship where the father was head under Christ, and over his family. Also taught that the Bible desired people to be fruitful and multiply and have lots of children because if they are raised in Christ they will help change the nation's narrative in favor of Christ. These are the teachings I was aware of and I agree with. It was more the individual cell groups that formed and shared the idea that patriarchy meant you had the right to decide if your kids married, and when married, the newly married couple had to receive the blessing of the father/father in law in order to make any changes within the family. Namely having children, moving, job changes, church choices etc... Not completely sure how wide spread these beliefs are. I have known some people who had no negative experiences with the organization as well.
Now, as far as Bill Gothards is concerned, according to many girls/women who worked near him within the organization, he would often take liberties such as being touchy with them and such. They would also be sent to his brother who is accused of doing more than being touchy. It has been a while since I read up on it but if you do a web search his name will be all over and you will find more information there.
