...Why? Why does he "need to"? Why doesn't he have a right to normalcy or privacy? He's earned that. Arguably more than any other superhero. What does it matter if Hannah Montana also did it? As if Hannah Montana is the originator of fictional characters having secret identities....As if Superman hasn't been doing this LONG before Miley Cyrus even existed.
It's one thing to not like him having a secret identity. That's perfectly valid. There are some heroes that I think would be better off going public too. But why are we acting like a superhero just wanting a normal life outside of their jobs is something that only pampered, teenager Disney Channel stars should want? Or that there's something inherently wrong with wanting to keep a low profile for himself and his family? Or wanting to do good but to still be looked at as a person and not a messiah? If he has the means to, he's well within his right to keep his personal life and his superhero life separate. I'd do the exact same thing in his shoes.
