In an atheistic civilization, morals are intrinsically fluid, and subject to change.
Actually, if you read your bible, you'll find that morals are just as fluid. Don't murder, except in certain situations. Don't lie, except in certain situations, etc. The difference between theists and atheists is that we admit it.
The natural goals of such a society can only be greed, might and power. It is survival of the fittest. He who owns the most, and controls the most, wins!
That's why here in the US, we have what's known as the "prosperity" gospel, taught mainly by fundamentalist Christians. Republicans and Tea-Partiers routinely support no restrictions on businesses, no taxes for the rich (well, Tea Partiers want no taxes whatsoever), as well as no help for those on the low end of the social spectrum. Both of these groups claim Christianity, not atheism as their driving motivation.
Atheism is worse than idol worship. Idol worship is polytheism, the belief in many powers.
No. Idol worship is the worship of an object, either as a symbol of a deity (like say, a cross), or as the deity itself. Polytheism is the belief in many gods, but does not require idol worship, nor does idol worship require polytheism.
It is possible to progress from many gods to belief in one God. The prime example is Abraham. Originally an idol worshipper, he eventually came to the knowledge that there can be only one true Power.
Actually, that's not a bad way to look at it. Well done.
The road from many powers to one power is relatively short, since the individual accepts in principle that there is something directing the universe.
People are not as fickle as you believe them to be. Changing one's beliefs takes time. If someone truly went from believing in multiple deities to only one deity overnight, I'd say they were either lying, or extremely gullible.
