Yo world builders, i got a question for you. How would you build a world where vampires and werewolves don't have to hide?

For example how would humans and supernaturals coexist without anything bad happening.<br>How humans would react if they found out that there are Vampires and werewolves (or any supernatural creature like witches, demons, angels, ghosts) in the world and how would everything play out? <br>And if you have an existing world with vampires and werewolves and they are in the public eye then tell me how that works.
