What is a key quality of a "zealous" supporter?

A "zealous" supporter is characterized by their deep commitment and enthusiasm toward a cause or belief. This quality manifests in their willingness to advocate passionately and fervently for what they support, often inspiring others around them. The essence of being zealous involves not just support, but a vigorous and active pursuit of goals, displaying devotion and earnestness in their approach. This strong emotional investment is what distinctly sets a zealous supporter apart from those who may show indifference, apathy, or complacency in their beliefs or causes.
