I think a similar problem is people viewing belief in nonexistent things as harmful. Another issue is religions tend to couple idealized personalities with higher powers when there may not be a need to do so.

The value of an idealized personality we choose to believe we can strive toward is to tap into and/or guide our intuitions in the moment, especially in times of internal/external conflict.

The value of recognizing/acknowledging the existence of uncontrollable higher powers in the world/universe is to instill humility & define one's own limits/boundaries.

Keeping in mind that that outlook generally includes things like "all meaning comes from christ" or similar platitudes.
