Morality does not require religion. Western Civilization's problems are not caused by the decline of Christianity. The West does not need Christianity.

Morality (or at least modern Western morality) did not really come from religion. It came from the Enlightenment. There’s also something called deontological ethics.
Atheism is simply a lack of belief in a high being, not hating God. You don’t really hate something that you don’t even believe exists.
When it comes to object morality, it’s still opinion, just God’s opinion.

The west is not going to go down under because of the lack of Christianity. A country can be highly religious & still dysfunctional.
