she raped Dick Grayson and was never punished for it. She briefly went to prison, but that was for her other crimes. It didn't help that, reading barely between the lines, Ms. Devin Grayson was projecting her own issues with sexuality and sexual trauma and crushing hard on a fictional character onto a character for no reason than to work out her own issues.
Okay, I have to say that I think you have to make a lot of assumptions about Grayson's life and personal history to make such a claim, and IMO the accusation borders on (if not crosses the line to) personally attacking her.
I agree that there should have been something more in canon confronting the rape as rape, but unfortunately it would have been impossible for her to be arrested for raping Dick without revealing his secret identity (not to mention it might have implicated Dick as an accessory to murder). She did go to prison, and as we saw in Secret Six a little while ago, it was one of the bigger/high security prisons and she was in there for life. And now she's dead.
Huntress gets called a Mary Sue because she almost always seemed to win her arguments with Batman about how far masked heroes were supposed to go, or at least Batman would rarely respond in a meaningful way. Every. Single. One.
I gotta disagree. Huntress's thing used to be that it's okay to kill people or be more brutal when the original crime was heinous. Batman's has always been that killing was wrong, and frequently espouses the idea that excessive brutality isn't usually effective or moral. Huntress eventually came around to Batman's side of things, but by way of Babs and the Birds of Prey's influence. In my mind those old 90s confrontations with Batman never seem to go anywhere, and neither one of them ever really "won" the argument.
