Is idolatry a problem in all of the world's religions or a problem in Christianity only?

Mostly Abrahamic religions pick out idolatry as a sin.

That's an interesting question, I hadn't considered the whole topic from that perspective, though I can certainly perceive the point, of course. I quite honestly don't know what to think of the whole premise, truthfully, my wife is quite devout on the whole topic, actuappy.

It's getting better: There is some hope for the human race.

I once went to Notre Dame for Christmas mass. Beautiful, ornate Gothic architecture with gargoyles and saints with symbols of how they died, and there was the most moving organ music coming from giant brass pipes that shook the walls and filled the air. The alter was made of stone. The priests and brothers were in long robes with tall hoods that covered them completely so you couldn't make out their faces. Then I realized that there wasn't a darn thing different from a Satanic mass. They had a lot of idols available at the gift shop near the back pews.

Last year at my local evangelical church, I couldn't help but notice that the symbol of adoration, the central figure to the entire ceremony, was a man on a cross. The whole congregation was smiling and singing, focused on a statue of a bleeding naked man being tortured to death. Just seemed a little weird to me that the God of Love demanded a sacrifice.

This year, I found a group inside a church where many people in the audience spoke to the group about ways of loving people, helping others, and encouraging education. A lot of them were older, highly educated and successful. They were very dedicated to peace, and supportive of the Constitution, civil rights, and the Universal Declaration of Human Rights. The church was called Unitarian Universalist, and the people were mostly atheists and agnostics. They didn't kill people by beheading or crucifixion, and didn't insist that everyone else believe their way or else burn in Hell
