I would agree that religion definitely serves as a propaganda service. But that said, religion does serve also as an ethical and moral service.
If one looks at both Nazism and Communism, both opposed to religion, one can see that where religion was missing, scientific barbarism became its
replacement.
As long as they don't force feed religion, both the church and the government (to use the Christian faith as an example), then who are we to oppose
the moral codes that people live there lives by.
