Well, at least she managed to escape the horrors of reading a classic novel that commits the unforgivable sin of not having the exact politics of 2020.
At this point, I think the issue is that there really is nothing that people with this kind of mindset truly "enjoy", or at least not in the way you and I would "enjoy" something. The average person is entertained by a book or movie that tells an engaging story, or is funny, or makes you ask questions. The books and movies the wokesters prop up are always more like essays lecturing about how oppressed their pet minority of the week is, and how evil everyone who does not belong to said minority group is by virtue of being born. But, really I can't imagine they're really "enjoying" reading something with little plot, no characterization, and that only has the goal of making you feel angry at people for their immutable traits. They only engage with media in order to have their views parroted back at them, not to be challenged, not to laugh, not to see a story unfold. It's why #WOKE comedy usually gets only applause, not laughter, the goal with these forms of entertainment is not to actually enjoy the thing, the goal is to pat yourself on the back for how much better you are than someone else.
As for why they constantly feel the need to shit on things that entertain others; I really do think that, after spending enough time in a #WOKE echo chamber where you have to constantly change how you speak, how you think and what you look at for fear of being #cancelled and dogpiled, you become a really miserable person. It's an ideology that tells you over and over, nonstop, that you are bad for traits you cannot change, and that nothing you do will ever make you less-bad because you were born bad, and so bad you will stay. I've seen it likened to religion before, and I get it, they've taken the concept of original sin and made it worse because at least sin could be forgiven, there is no forgiveness to be found here. It just sucks the joy out of everything, and when you're constantly miserable, surround yourself by people who tell you you deserve that misery because you are bad, and then you see people laughing at jokes, or having fun with a book or movie, it makes you angry. Because you've been trained to sniff out anything that could possibly be seen as offensive, and even if the people you are getting offended on behalf of tell you it doesn't matter or that you are looking at it the wrong way, it's still your job to get upset about it. Maybe they think that, by tearing things down that they've found a way to twist into being problematic(TM), they can begin to atone for the original sin of being born bad. They can show they aren't like the other white/cis/straight people, and they care about the struggle and they will help, by... yelling at people on Twitter for liking a book which was written by someone with the wrong skin color. IDK, this is Autistic, but it's the best motive I can think of for this insane behavior.
