I tend to think that much of western societies problems lay not so much in what you term "idol worship" (following the teachings of Jesus, allah, buddha etc) Which I feel most practicing these various faiths are not into blatent idol worshop...
I feel the real problem the western world faces is the worship of material objects such as houses, cars, rolex watches, etc.
I think it would be a good thing if people really followed the teaching of these great masters.
The suffering that is caused by our wanting these material things is what disrupts the discord in harmony, and causes conflict, violence, and war.
Not condoning communism as a solution, nor am I advocating capitalism, each has it's various pluses and minuses. I am condoning the "middle road" called moderation!
