Fear involves loss.

What is fear beyond a belief that something will be lost and gone, possibly forgotten, that you may hold most dear? Fear always involves loss. Just as much as anger grows from fear, fear grows from loss. When you lose influence, when you lose your voice on a particular matter, when you lose the voices of others who share your concerns, there can be a response most clearly identified as fear, and as a result of that fear, anger can arise.

You cannot go through life without fear or anger. You cannot go through life without even a temporary commitment to a certain set of beliefs. When those beliefs are challenged, then there is the threat of loss, and when there is a threat of loss, the fear increases and actions may result as a consequence of that fear. Anger frequently accompanies such actions.
