Although this is also just a belief - your personal belief.

Ultimately, beliefs are always of the utmost importance, because beliefs are what drive our actions.

The problem is that some people put a lot of stock in certain beliefs that are based purely on someone's speculations and imaginings, rather than on things that everyone can relate to.

For example, believing that you'll go to hell if you don't believe in Jesus is pure speculation. Whereas believing that everyone appreciates a tasty, nourishing meal and caring neighbors are things that everyone believes already.

Beliefs are always important, because they drive everything else. The problem is that some people believe things that breed tribalism and separation, rather than believing things that would bring us all together.
