Why do people hate Taylor Swift?

I'm honestly curious and confused about why people hate her. In my opinion her music isn't bad. And she isn't a bad person either. So why do people hate her?

I just feel like whenever I talk about her, there is always one person who gets mad. Whenever I don't like someone favorite artist, I don't tell them there wrong.

I'm not trying to be rude or anything. I'm just trying to understand.

EDIT

OMG, I did not expect this to blow up like this. Thank you all for commenting and sharing your thoughts. I try to be optimistic about everything and this help me a lot. 💛
