A writer is one who communicates ideas and emotions people want to communicate but aren't quite sure how, or even if, they should communicate them.
Christianity, like genius, is one of the hardest concepts to forgive. We hear what we want to hear and accept what we want to accept, for the most part, simply because there is nothing more offensive than feeling like you have to re-evaluate your own train of thought and purpose in life. You have to die to an extent in your hunger for faith, for wisdom, and quite frankly, most people aren't ready to die.

People don't want children to know what they need to know. They want their kids to know what they ought to need to know. If you're a teacher you're in a constant battle with mildly deluded adults who think the world will get better if you imagine it is better. You want to teach about sex? Fine, but only when they're old enough to do it. You want to talk politics? Sure, but nothing modern. Religion? So long as you don't actually think about it. Otherwise some furious mob will come to your house and burn you for a witch.
