What christians get right about deconversion

I've been following Christian theologian and apologist Randal Rauser's interview series with apologist John Marriott on his book about deconversion and how to prevent it. 

There is quite a lot I'd like to say on the topic, at least in critique of why John's (and purportedly Randal's) solutions are ultimately not good reasons for someone to remain a Christian; but that's not my aim today. 

Here I want to offer some agreement with their assessment of deconversions and one key area of why they happen that they touched on in their final post in the series.

The idea is that of plausibility structures and how Christians need to maintain a plausibility structure through the use of their churches.
