Everyone is unique, from a psychological standpoint and we have different needs. Why can't someone believe something on faith, if it makes them a better person and also their belief does not force them to reject reality, which is clearly not the case with Armoured. You act as if everyone should think as you think.
Now, when someone needs to reject reality because of their faith and or has convinced themselves they have objective evidence for their faith (when none exists), I would agree, you likely have someone who is only playing games with themselves, engaging in confirmation bias and turning a blind eye to obvious objective evidence. With some, this is the case, with others, it isn't.
