Shame you got downvoted.

Although it's not conclusive that absence of religion is worse than religion itself, there's tons of evidence for it (e.g. communist & fascist atrocities, medical experiments) – I'd wish that secular believers were more self-critical and introspective.

My biggest concern of modern culture is the sense of inevitability. That progressiveness by definition is beneficial, without any sort of reflection. May things have regressed, and we should take account of the many benefits and setbacks.
