Any time someone tries to convince my they have the absolute truth I make sure not to drink the Koolaid.

dogma, ideology, or faith aren't really judged by a standard of absolute truth only by functional truth.

I might believe that I'm held to the ground by magical strings held by a wizard at the center of the earth while you believe its gravity while my belief may be far from absolute truth we both still gain from the functional truth of our belief and by conducting our live accordingly.

If you where to threaten my faith in the wizard I might very quickly appear to be excessive in my adherence to dogma after all your threat might end with me floating of into space.

Passion is valuable but most wouldn't kill or die over a zeal for knitting despite the warmth provided by a well knitted scarf.
