Does the decline of religiosity in society bother you?

[sting in the rafters]

Organized religion? Not really. The institutional strengths of clergy, Astika, imams, rabbis, etc. have long outlived their medieval functions of preserving traditions/cultural information. In contrast, they very much contribute to suppression of thought in some cases.

Spirituality in general? Eh, different strokes for different folks. If one feels an existential need for a higher belief system, that is their prerogative. However, I don't think society is suffering because we no longer visit the shaman when we're sick.
