>Religion today is primarily built from culture rather than faith in a deity
Oh I want all people who are not entirely agree with every word in thier chosen religion, all postulates, everything - to be excommunicated, just banned to call themselves a follower of a certain religion.
You just can't be an adept if you don't believe in it entirely.
"Yes but", "good ideas but", "something is right but" - that's not how you approach a religion! If you call yourself, say, a christian, I should expect you believe all things christians believe.
If you choose to accept only
some of them - that's normal, in fact - we all do in a way (any religion, I think - I'm sure there a couple ok ideas here or there anyway) But that doesn't make you a christian.
As for your point - I'd say it was pretty much always about culture. Feeling of being together, sharing mostly basic ideas, being connected within your community and find connections out of it, away from your birth place - expecting compassion, shelter, help from strangers who happen to share your religious beliefs.
>The death of The Simpsons didn't happen by season 9, but rather after the Movie in 2007 (season 19)
Also have this, you all: Simpsons are not dead.
I don't think someone perceive season 2 with the rules of season 9, why then you should see season 25 in terms of season 9 or 10 or whatever.
