You're redundant! and maybe being pretty homophobic, guy, seriously Also, Dark Knight Returns isn't in continuity. It never was, it was just a sort what-if tale they let Frank Miller tell because he couldn't deal with the fact that he was about to be older than Bruce Wayne.
And Bruce is totally gay for Clark, but they'll never get together because Clark likes Lois better. And even if Bruce wasn't, they're a lot better as friends. If you want superheroes who hate each other, go read Marvel.
