My mom used to bitch when I was a teenager that I was going to get everyone pregnant and ruin the family. Like I was just a large cock with legs. It wasn't going to happen, but her words and admonishment were in the back of my mind every time I tried to start a relationship. It colored my whole perspective on responsibility and I over corrected to the point of talking myself out of talking to girls most of the time.
Lyriel's life is supposed to be about majesty from what she's been told. But she sees humans lusting after elves and those elves -her family- accommodating them. She too has had her perception of sex warped poorly. She believes sexual gratification is something to be above or be conquered. Fortunately, she seems to be disassociating what she expects the world to be and is having her childish absolutes slowly left behind. One day she's simply going to ask to get fucked without the pretense and guilt about her own feelings and it will be a glorious day for the household (and probably Rae lol).
Was she racist? YYYYyeeeeeeeeeeaaaaaaaaahhhhhhhh, I guess. But considering what she grew up around, I can see why she was upset. It's nice to see her change her mind because I love her "volleyball" body lol
