Superman recently released his identity to the world as a gesture of trust. Previously, Lois Lane released his identity because a villain had found out about it and was trying to use it against him. Batman released his identity to Gotham in the White Knight comic as an appeal for people to trust him. And Tony Stark did his reveal in the MCU as a gesture of audacity and flamboyance. (He couldn't properly cover it up, and he's too egotistic to not be a hero). For various reasons, the secret identity concept - used keep your close ones safe by keeping your hero and private life separate - has been broken over comic-book history. I'm speaking in terms of outright public disclosure, not traditional revealing to only a few special people. As a social gesture, disclosure of identity invites trust and cuts away double life complications, but also draws attention from bad guys. When Tony Stark revealed himself, he got attention from the US government and rival scientists. But as an individual, a secret identity allows a sense of privacy which all people should have. Superman values his Clark Kent identity because it's not just a disguise but a part of him, that allows him to rest at Kansas away from the troubles Superman is needed to resolve. Even Superman needs to rest in body and spirit occasionally, and constant public exposure/celebrity status can hamper that. So the dilemma is: are secret identities for superheroes still worth keeping, or should they be retired?
