Are you implying that there is another religion on Earth that all believers agree on every aspect of completely? Atheism included...We all have different experiences, were raised in different environments, have different values and morals and therefore different beliefs and viewpoints. There are certain aspects of Christianity that require belief in, or else excludes you from being a Christian (such as that Jesus Christ died and resurrected).
Your statement lacks critical thinking. Even if every single person of a particular faith held the exact same views, they could all still be wrong. Majority opinion does not equate to truth, my friend.
