I've been thinking about this, and I think G-man is right about Batman being pro registration, and Superman being against registration. I think Robin would side with Batman, but Nightwing and the original Titans would probably side with Superman. Add Ollie and Hal to the pro side. Wonder Woman would probably be against it because she's seen the system perverted against her. Oracle would be against it, and her Birds of Prey would stand by her, including former BOP member Canary. Jay Flash would be against it, what with his own identity public and his experiences with that. Bart Flash would be for, because there needs to be a rift between "grandfather" and "son," much like Bruce vs. Dick. This is a civil, or rather, uncivil war, after all. I think the real impact would be which side Supergirl falls on. She is supposed to be more powerful than Superman, and if Batman could bring her over to his side, well...
