A belief system cannot be justified through feeling or emotional appeal to the individual alone. Cultural or societal context is required.
For example, a person cannot validly claim that wiggling their toes in the mud is the most important thing. It’s invalid because it cannot be understood without some kind of justification.
Perhaps the person can claim that it is spiritually significant as it allows you to connect with nature. But, since a justification has now been given, it can be questioned and debated.
