I’ve addressed this head on by examining how the environment at the Honor Academy squares against typical cult characteristics. You can read the posts here:
Is Teen Mania a Cult? Conclusion
Update Nov. 2010: After over a year of running this blog, hearing stories from many former interns and dealing with TM leadership, I am more certain than ever that the environment at the Honor Academy is very dangerous – spiritually, emotionally, mentally and physically.
Teen Mania has repeatedly refused to repent for their past abuses and continues to foster an authoritarian environment where interns are taught to ignore their own discernment and bodily pain. Under no circumstances would I recommend that anyone participate in this program.
