Interesting view. Religion is a necessary foundation for our civilization to function but I believe its true meaning was lost a long time ago.

We need religion to help control mass populations and provide a core principal that that population adheres to. This causes issues and war when conflicting ideologies mix since neither side will provide any leeway.

The "esoteric" principals of religious movements are more important as they help develop the spiritual understanding an individual has and brings forth the commonly observed ideas of many mainstream religions.

My opinion: Modern day religions are no longer needed as they are tools for conflict, but, the esoteric/soul development that some religions offer is still very much important. They help guide young believers down a life path that will see them treat others with respect and dignity opposed to oppressing others' views.
