The writer wants you to think the Celestial Dragons rape a lot. It's a plot device he likes to use, now.
It's uncomfortable that it's expected to happen regularly. Garling hiding a kid was one thing, but now that the author has suggested they go through convoluted plots to do it beyond what was assumed with the slavery stuff is a bit crazy.
Before Ginny, there was only assumptions about rape and a single instance of it doesn't constitute a pattern.
Garling didn't rape, but he killed the woman and tried to take the kids. A similar thing happens to Candel in Shuri's case, but Candel was raped.
The writer has told us to "read between the lines" as adult readers. This means we should be assuming Doflamingo raped Viola too now that a pattern has developed. The same goes for Nefertari Lili and Imu.
That's 4 cases of it. Viola, Ginny, Candel, and Lili.
At this point, it could be said that the Devil Fruits and Haki are flimsy pretexts for sexual violence.
(he already did this once in Dressrosa btw)
