But this is an exercise that is best performed by you. It is about changing your own attention. Next time you come across some "adult convert", instead of looking for signs that prove your assumptions (that they are looking for comfort), look for some positive sign.
Consider how you are reacting to this very comment chain. Are you thinking "there is no possible way any person could ever be attracted to religion for any other possible reason than fear and need for comfort". When you asked me for suggestions were you actually curious? Bring that same curiosity to your next interaction. Demand of your own attention to see a positive reason.
And consider that if you are not able to notice the positive intentions in the actions of another, that might be a you problem.
