I don't think DC has anything against women. That, in itself, would assume the company even
has an agenda. Which isn't true. Except, of course, to make money.
The reason all the women are getting it is....well....all the heroes are men. That's just the way history has created this for us. If they want to hurt the heroes by striking closest to them, then, they go after their women. Nothing more, nothing less.
I have noticed that the pattern of death so far is related only to those with public id's. Therefore, one has to wonder how the killer (assuming it isn't someone they know) would know to strike at Tim Drake's father, as Tim is quite private with his secret. Although, everyone and their mother knows who Batman is, so, maybe this is the only logical connection for the killer.
I've noticed that the Superman and Flash creative teams must have gotten the heads-up on this series. Lois Lane and Linda Park are conviently absent during this entire story. Guess Geoff didn't want anyone playing with his toys. Funny how he used Hal as Spectre to wipe the world's memory of his ID
right before
Identity Crisis. Was that Geoff trying to pre-cement this new revelation into the DCU prior to IC, or, just protect his own book?
Also, I am still convinced that someone is/has messed with Ralph and the League's mind. When we first see the Sue/Light incident, it is shown through the memories of Ollie and Ralph. When we see it again, it is through Light's memory.
I think Batman was involved with it. I think he was involved, and, had his presence erased from the rest of the heroes, for reasons unknown. Perhaps, he convinced getting Zatanna to wipe everyone without their knowing? That way, he could keep tabs on even them, watching/knowing everytime they may step over the line? I don't know. Just rambling theories.
Doc, I like your Firestorm theory. It would seem to fit. Though, what they've got that can stop the Nuclear Man, I don't know.
Maybe the killer is Ron Raymond? Maybe he finally went schizo trying consider all the different voices he's had in his head over the years. Grimm, as he has told me, believes it to be Martin Stein (the other half of the original Firestorm duo). He said last time he was seen, Stein had lost his mind. Another strong possibility.
Maybe the killer is Batman?!!

I wish.
I certainly hope Meltzer delivers on this...
