So I guess you're going to conveniently ignore the elaborate conversation between Superman and Batman in The Dark Knight Returns where Batman informs Superman that he "could have beaten [him]" but that he didn't -- allowing Clark to remember for all time just who DID beat him in the end. And then in part 2, it becomes clear that Superman has, in fact, accepted his loss to Batman.

Convenient, no? Let's not go ignoring important things here ;)
