So Damian is not just a jerk, he's a sexist jerk. Nobody, and I mean nobody should use batgirl or any other female super hero as a means of negative comparison to a male member of the group as a sign of mockery in my presence. You not only mock the person your talking to, but you also mock every single female hero out there who puts as much on the line for justice as these guys do.
I'd like to see Damian say that again after he gets shot point blank in the stomach and becomes paralyzed from the waste down.
