Not just because she hijacks the narrative away from the protagonist and forces him (and all of the characters around him) to behave in horribly OOC ways, but also because the mentality underlying her story here - as explicitly stated by the author herself, lest anyone accuse me of mind-reading - is so morally wrong in my eyes that I have a hard time even talking about it in terms that are appropriate for this comm.
In talking about what happened between Dick and Tarantula, Grayson insists that there's a difference between "rape" and "non-consensual sex." To me, that's simply wrong - non-consensual sex IS rape, by DEFINITION - and since so much of the rest of the story flows from there, in terms of how we're meant to see the relationship between these two ... well, not only do I find it to be a badly-WRITTEN story, but I also consider it bad on a MORAL level. It's how I felt about Civil War when Mark Millar and Tom Brevoort had insisted that "the right side won" at the end, or when I read Sally Floyd's screeching wall-of-text about what it means to be "a true American" in Frontline, or when Norman Osborn was put in charge of the Marvel Universe, when Bendis had argued that Norman would make a "better hero" BECAUSE he's evil. Not only do I find the characters to be OOC and the plots to be internally inconsistent to a degree that cannot be reconciled, but I also feel like I've stepped inside the mind of someone whom I would cross the street to avoid in real life.
And once again, if you put any female character in Marvel or DC in the same situation as Dick, and then had the writer try to present it as merely questionable consent, rather than as full-on rape, then no matter what any of you say to the contrary, I know for a fact that there wouldn't be nearly this level of apologist defense-making from fangirls, AND RIGHTLY SO, because it's WRONG to defend that shit, regardless of gender, but because Dick is a MAN, everybody suddenly turns into the characters from the South Park episode who can't believe that a man could get raped by an attractive woman (or even if he could, it's not THAT bad, because deep down, he secretly WANTED it, and Tarantula just PERSUADED him, and ASDFJKL;).
... You know what? I'm gonna put my cards on the table right now. The first time I, as a guy, had sex with a girl, all the way back in my college days? It did not happen with my consent. Under the exact same circumstances, I know exactly what I would call it, if it had happened to a woman, but because it happened to me, I find it nearly impossible to even TYPE the word in the same sentence as what happened to me. I was raised to respect victims of rape by acknowledging what had been done to them for what it was - not "dub-con, not "reluctance," not "persuaded sex," but RAPE - and yet, even with that grounding, I'm so fucked up from all the ingrained societal double-standard bullshit surrounding this issue that I can't get my own head straight about what happened to me - and, hey, I'm guessing I'm not the only guy who's in this boat - and THIS is the scene where Grayson is going to choose to portray flat-out rape as QUESTIONABLE consent? REALLY? With all the diminishment of male rape victims that happens in society, THIS is where she thought it would be a good idea to try and MUDDY THE WATERS EVEN FURTHER? FUCK THAT. This is UGLY and TRIGGER-INDUCING, to a degree that wouldn't even be tolerated in FAN FICTION.
