Yes, it's dying in developed countries.
No, it's not dying in underdeveloped countries.
no, even on developed countries religion isn't dying.
religion this days adapt to what people this days think. its always been that way.
remember christian dark ages ?
it happens because christian on that times think that invention and innovation doesn't match with christianity, and when after the "christian" can accept the change, things getting better, more practices is accepted and many more.
and today.
let's talk about hijab, burka, and things become more popular and adaptable.
people become more open with this kind of fashion and philosophy.
this is how religion adapt with people, vice versa.
but thats just my 2 cents.
