Well, I, for one, don't hate her. (And her Leo Rising pop-star status is just assumed). But what is the all-consuming predilection her fans in particular have for her? What does Taylor's "image" represent to young(ish) women that's so desirable that has made her a cultural icon above nearly all others?
As her songs, though competent, are none too memorable. (Unless she's written one about you).
I think some of it is the time we live in. Many need something that gives them meaning and belonging to a community. Something they can gather around that isn't too complicated to understand and gives them a break from all viciousness.
We can see this need in other aspects of the world. It's a trend now on social media NOT to post a lot of content from your own life. Rather consuming others' contents. And NOT pressing "like". People seem to want to shield themselves more.
Also, churches are seeing an increase in number of younger visitors.
I think it's all connected, and that it's because of the state the world is in.
It's Taylor Swift right now. But it has been others in the past. And it will be others in the future.
