Hypothetical? Obviously not. Including elements about rape, murder, sexual violence, or world-ending catastrophes? Probably the last one, but otherwise I don’t know what is in comic books nowadays, as I know longer read them. Offensive to some? Well, probably in its implications that grown damn adults should not read comic books. But I would read comic books if my eyes worked, so there.
When John Byrne rebooted superman in the 1980s, one major and, to my mind, well-thought change was that superman no longer acted as if he had a secret identity. But that was at least three or four continuity reboots ago, and during one of those I stopped even checking out trade paperbacks from the library on account of retinopathy. So I am hardly up to speed.
So I will repeat the question contained in the thread title: Does Superman, in current continuity and slash or the movies, still hide his secret identity in plain sight by simply pretending that he doesn’t have one? Whether the answer is yes or no, is that elegant deception any less dishonest than what Batman (whom I highly suspect of being both an embezzler and a tax fraud) regularly does?
