I can see your point that it's really not appropriate to bring darker themes to a work that didn't intend to have those themes. That's fair. And for the record, I don't think the Braintrust meant for the scene to be read as a rape. However, I... get kind of touchy when I hear that argument. (As I showed, sorry about that.)
Because, in my opinion, just because a story didn't intend to tackle darker themes doesn't mean they're not there. It doesn't mean that the audience is wrong for reacting to a certain plot element like this (and I have to admit I hate how consent issues are brushed aside in these kind of stories). Does it mean these themes shouldn't be explored? That's a question I can't answer. I know I don't want it showing up in every comic I read.
I guess what I'm trying to say is that I agree it wasn't intentional. And I agree, it's often not played like rape when this happens. I just find the "it's not what they intended so it's not rape" kind of dismissive.
