With all due respect, Religion being an emotional crutch is the sort of thing you say as a teenager when you are in the first flush of serious irreligion.
Firstly, anything can become an emotional crutch, secondly the times and places where religion cannot be and as some Christians have observed the good news becomes bad news for your ego before it can become the good news. John Bunyan is such a Christian.
I remember a documentary about two friends an observant Jewish businessman and his accountant, a non stipendiary Anglican minister. The Anglican commented on how lucky his Jewish friend was having his religion codified. Christianity? Not so easy and Jesus commandments entail a lifetime of navigation and learning and the difference between doing and being. Hardly crutch material.
With all due respect he didn't say anything about an emotional crutch
