You were talking about Ashe's behavior. No matter what she does, she is much more reserved than Natasha. Therefore, this is precisely a matter of discrimination. Yes, there were real cases when duplos lost control, according to the developer, but mostly this was discrimination. This can be understood by the fact that Rachel and mother are not worried about Ashe's problems, although they know that she is duplo.I didn't say it wasn't. Monos seem to be the men of this world. Men sexually assault and rape women with alarming frequency as it is. I would imagine those statistics are still similar in this world.
Now imagine I told you there was a group of people even more sexually depraved than men. With vastly increased libidos and urges that they can't escape because it's a part of their DNA. I'm sure there's a lot more that goes into the why of rapists, but it isn't a strange idea that people might begin to fear this group.
