To draw a distinction:
Atheism: There is no God.
Agnosticism: There is no way to tell if there is a God.
Apathy: I don't care whether there is a God or not.
"Europe seems to be generally adopting: a total lack of interest in whether or not there is a God."
In the not too distant future uncommited Europeans will be given the chance to accept Allah or have their throats cut.
Well, that's my attitude exactly.
I believe you are correct. Europe is given over to hedonism. Their attitude seems to say that there is no point to any of this life except the pleasure one can get out of it.
There is no afterlife, or at least nothing I do will affect where I end up. There is no right or wrong.
Such is the darkness of Europe.
I think you are right in suggesting that what is really happening is apathy. In the past, Christianity held such a prominent position that it was impossible to simply be apathetic about it, and most Atheism is a reaction to religion. Apathy in some sense represents the victory of atheism, not its defeat: whereas once it was important to disprove god, people now don't even think about it. For what it's worth, I would probably fall into the apathy because of agnosticism camp.
