In those two panels, in that one gesture of Batman contemplating the Robins he’s lost in front of the symbol of those losses, that line of suits in cases, the glass ceiling keeping girls out of the red and green and gold costume at Batman’s side finally cracked and fell.I'm not taking this as DC has gone feminist. But they've noticed that female fans read female characters, and given in to a reasonable request in order to please those fans.
Most importantly, the idea of female fanbase for Batman comics is in their heads, and it's a fanbase they'll market to.
And on the whole, this is pretty damned impressive from a Green Lantern fan's point of view. I mean, it took ten fucking years to get a straight white male lead's mischaracterization retconned into mind control on our side of the fence.
