Batman has a secret identity, right? So Bruce Wayne has to walk around every second of every day knowing that if somebody finds out his secret, his family is dead, his friends are dead, everyone he loves gets tortured to death by costumed supervillains. And he has to live with the weight of that secret every day. But not Tony Stark, he's open about who he is. He tells the world he's Iron Man, he doesn't give a shit. He doesn't have that shadow hanging over him, he doesn't have to spend energy building up those walls of lies around himself. You're one or the other - either you're one of those people who has to hide your real self because it would ruin you if it came out, because of your secret fetishes or addictions or crimes, or you're not one of those people. And the two groups aren't even living in the same universe.
