@xris,
Some things about Gnosticism - it's not Satan who is God. Instead, Gnostics reason that since God created the world, and since the world is imperfect, God must also be imperfect. This creator god is called the demiurge. The demiurge is not necessarily pure evil, only imperfect. Gnostics associate the demiurge with the God of the Old Testament.
Later movements, like Catharism, did develop the Gnostic notion of a demiurge into the idea that God is Satan.
To call religion absurd because religion lacks objective standards does not make much sense to me.
To call scripture fact is to miss the point. Scripture is not fact, it's mythology. Interpetation must exist because no two humans are the same.
No single religion is right and all of the others wrong. Consider:
You want to look at the moon so you ask your friends to point at the moon. Each friendpoints a different way according to their perspective, and so each hand is different. The object they point at is the same, but the directions are all different. Such is religion. They all point to the same thing, but in their own unique way due to social and environmental conditions. Diversity in religion is good.
Democracy and religion can coexist quite easily. Democracy requires diverse perspectives to be embraced, and religion also benefits by this practice. Religion isn't about being right and wrong in any logical context, religion is about cultivating compassion.
