Harvey Milk and the city of San Francisco gives many people the "permission" they need to fight for gay rights in other places. The Castro became a symbol of this permission and Milk's legacy has since spread across the world. Today, a day before the 40th anniversary of his death, we look at Harvey Milk’s message of hope through the eyes of one man who watched, admired and acted on that message.
