Then you can read Batman, Streets of Gotham, Gotham City Sirens, Detective Comics, Red Robin, Batgirl, Justice League of America, Final Crisis: Batman, Batman Confidential, and Azrael. Not to mention all of the AU/Cartoon books. There is no shortage of comics about the world of Batman.
But I think the argument is out of control because I disagree with the premise that the Grant Morrison's Batman is, intentionally or not, inaccessible to hardcore fans of the Batman universe. I'm not sure where Batman and Robin is going at the minute, but large portions of his (Adjectiveless) Batman run were continuity jerk offs.
His stated intention wasn't just that people with a vague understanding of Batman can pick up a book and read it but that everything they ever learned about Batman was true in some way. That's why you have things like the Club of Heroes, Batradia and Bat-mite, Damian and Old School Batwoman.
Many of Grant Morrison's stories have a stated theme rather than just comic book story telling. You can take it or leave it (or simply find it inexpertly done) but since New X-Men his crash-bang-boom comics have always had him reinvisioning how classic characters deal with a changing world and what that meant both for them and for the reader.
I think Batman and Robin is too young for me to really decide what I like and don't like about it and if what it is doing is successful. But I think Batman:RIP was an excellent deconstruction of Batman as a hero and a rather terrifying look at what happens when the world stops making sense. Looking back, I think I would have had the same reaction if I didn't know about all the classic stories but I know I enjoyed putting them together all the same.
