Good-faith practitioners of religions should be able to acknowledge:

Everyone's belief in god or religion is just a guess, and no one's guess is better than anyone else's. There are many religions. All of them can’t be right. All of them may be wrong.
No religion is inherently good. It's only as good as its practitioners choose to make it.
For whatever good religion does, it is also a source of tremendous harm to humanity. Good practitioners of a religion should call out those who use it to do harm.
Religion will never unite humanity or be a source of common values. There are too many different beliefs (even within a single religion), and religion is too easily misinterpreted, misunderstood, or manipulated and corrupted.
