What are facts about separation of church and state?

Answer 1

The fact is that the separation of church and state is often misinterpreted. It was not meant for people to use it to keep Christianity out of the U.S. government, but it was meant to keep the government out of the church. That is what England was doing and many colonists were different denominations and did not want a specific denomination to rule over the U.S. They wanted people to express their denomination freely, not become this radical hype many have turned it into.

Another answer:

The reverse is also true in that religion should not interfere in rights under the constitution. One religion's view of a right may not be the same as another religion and neither interpretation of the law should be selected over the other.
