There are different kinds of crusades – moral, political, environmental, and even anti-war ones. Sometimes sanctified and sometimes spur-of-the-moment, they can quickly take on a life of their own – overflowing their banks and overwhelming the very leaders who got them started. More than a movement, but not quite an army, crusaders gather together under one banner and are driven by a single vision. Neptune in Aries can create an atmosphere where you get caught up in the zeal and appeal of a popular cause, and once enlisted you will fight to the finish. Hopefully this is more a battle of ideas than a battle of fists because the latter can get bloody. Mars, ruler of Aries, was named after the Roman god of war, so there's an us-versus-them animosity streaming through this Neptune; however, the energy can be redirected into more positive outlets like healthy competition, vigorous contesting of staid norms, and a celebration of individuals who rise above the fray. Your crusade shouldn't be focused on just fighting the good fight, but on ennobling and improving the lives around you.
