I think the rape stuff is more on the individual author than the Omegaverse—even though it does do some fukt stuff by attributing rape to passion and a biological instinct rather than culture and subjugation and also linking anatomy, dominance, and giver/receiver roles—I’ve read plenty of stories that weren’t about one partner forcing the other, but rather two people who are really into each other having passion overcome their reason and give in to their feelings.
All this is to say, I think in this particular case, as far as we’ve seen through the first chapter, all of this could be achieved with or without Omegaverse dynamics—except maybe the late-onset sexism. I think talking about Omegaverse and what it does is probably warranted given this is the first work on Dynasty (at least to my knowledge), but I think most of what’s going on is the author’s decisions about how the story will go, largely independent from the Omegaverse background. Does that make sense?
