If your goal is to make those whose theology you're debunking happy then I would agree with you that a case by case assessment is necessary.
The many different circumstances that people come to accept religion through along with the many different ways people integrate religious beliefs into their lives mean that the benefits of religious belief so far as happiness is concerned have more to do with the individual than the dogma.
Personally I find the support and development of the consistent idea against the inconsistent popular idea to be more gratifying than a combination of pussyfooting and back rubbing in an attempt to keep a mass of perceived inferiors happy.
And to keep information you hold as true away from others due to your belief that they would lack the ability to properly manage it is absolutely a stance of superiority.
Would you rather treat others with respect or kindness?
