A few years ago, John Becket wrote a couple of really useful articles on escaping fundamentalism, which I recommend reading if you are an ex-evangelical or an ex-fundamentalist.

• John Beckett (2015), “Escaping Fundamentalism.” Under the ancient oaks.  
• John Beckett (2020), “Exorcising Fundamentalism: The steps on my journey.” Under the ancient oaks. 

I also made a video on this topic, entitled Recovering from Fundamentalism.
