You are a member of a group of magic users in a modern-day Earth. Your group has some significant number of people, but is still a stark minority of the world's population (there are about 6 million people, generally scattered throughout the world). Anybody could be born with the ability for magic; it is completely random (i.e. having two wizards for parents in no way changes the odds having a child with magical abilities). The magic you can perform is "Harry Potter"-esque.
Magic users have been around for centuries, but have had tenuous relationships with non-magic users. Indeed, in the past, whenever they've tried to reveal themselves to the general population, they've been branded heretics, hunted and killed.
However, generally speaking, there aren't really any evil magic users. Sure, you get the occasional megalomaniac, but in this magic system, any extended use of destructive magic, or magic that causes harm or pain to others, greatly weakens that person's power, and they are easily subdued. E.g., you could use magic to kill someone else, but after doing so, you lose all magical abilities for a period of time. Suffice it to say, magic users today are generally a peaceful, productive bunch.
Concerned with all the turmoil around them, your group of wizards decides it is time to reveal themselves to the world. They are convinced that their powers can be put to much greater good if they can wield them openly. However, based on historical precedence, you are also concerned by the fear and backlash that might ensue from the rest of the world.
How do you reveal yourselves in such a way that the world openly accepts your group of magic users?
