What? No wonder the anti-science movements are growing again if being accurate and realistic is seen as a bad thing. It's anti-intellectual post-modernism nonsense. There's the truth, and then there isn't. How is it just as bad to say "there is no god, and that's good, because religions lead to trouble so should be kept private" as it is to say "You don't believe what I do, you're going to suffer for eternity."
I've been accused of some things in my time, but anti-intellectual is not one of them. And do you even know what you mean by "post-modernism"? Your response is a straw-man.
When I talk about people, I talk about human beings who think and feel and who have emotional as well as intellectual needs. Belittling people for their beliefs, making them feel stupid and worthless has an emotional impact just as much as telling them they're going to rot in hell, so no, morally, I don't see a difference.
I can't think of anyone I know who, because of their religious beliefs, is not interested in how scientific understanding has pushed back the boundaries of human knowledge on an unimaginable scale in recent years (that's not to say that people like that don't exist as that's self-evident). There are massive, complicated, unanswered questions about - in Douglas Adams' words "Life, the Universe and Everything" that science has not only solved, but has posed. It is not even close to answering them all.
[EDIT, just to clarify: what I'm saying here is that to suggest religious belief, at a general level, is incompatible with scientific endeavour is palpable nonsense. Scientific rigour and deep questioning using one of the the universe's most bewildering characteristics, self-awareness, to find answers to your emotional needs are just parts of the same continuum.]
Religion is persistent because it allows people to think of themselves as part of a bigger sense of consciousness. A thought that might go something like this: "Millions of years of human history of which my lifespan is but a flicker, and yet still the Ultimate questions aren't revealed to us...but perhaps this ancient knowledge has the answers that we're just finding our way to?"
That's not anti-intellectual. Wishful thinking, maybe, but it gives people something that they can hang their questions on and makes them think that their life is worthwhile. You may wear your cynicism and pessimism on your sleeve, but you needn't force your beliefs on [others]: that's just as bad as what the fire-and-brimstone preachers do.
