I know you mean Meltzer's JLA, not IDENTITY CRISIS, but I can't help but recall this piece where it was revealed that editorial, not Meltzer, wanted Sue Dibney to be raped because, in the words of a certain editor, "We need a rape."
So yeah, I'm not sure how much of Meltzer's run you blame him for, but more and more I'm willing to blame DiDio and his editorial minions for the shit that happens in superhero comics.
