Yeah, but this would be her title as a hero. I don't think she'd be worried about too much respect in that sense. I mean, woman=/=ma'am, and I don't think she'd have a problem with Ms. either. I can't imagine any younger male hero insisting on being called ___guy or ___boy over ___man. I think they see man as the one with the most dignity. I don't think Barbara want to be talking to Catwoman and Wonder Woman as Batgirl, especially after being Oracle, a name associated with wisdom.
