Fortunately or unfortunately I have not come across this in my playthroughs but I also have very little to do with Halsin in most of my play sessions.
I am sorry for your experiences as a SA victim and unfortunately this is a reality in both the game and in real life. But I agree it could have been handled better by Larian in the story. I did google the spoilers for that story arc in question and yes it is a bit... tasteless, to put it politely. But I am going to chalk it up to another one of the small criticisms I have with the games writing. Like the number of same sex couples that have biological children together... somehow.
