Western culture is NOT decadent?..
This is gonna be good.. how do you support that concept?..
True Islam is more or less Satanic.. at least Islam is what Satanic would be if there were a Satan.. Pretty much Islam is Satans bathroom and Western Culture is his trash can.. Satan seems pretty much at home on this planet.., currently..
If it turns out that there is a God, I don't think that he's evil. But the worst that you can say about him is that basically he's an underachiever.
