I can pretty much nail this one on the head, people have various reasons but the main ones would be.
a) she has sold way more than most of their faves have since the year 2000
b) she writes her own music and it actually sells
c) she has dated people they want to nail
d) she won a grammy for ATOY which most of their faves haven't and probably never will (bar 2 or 3) for an album she not only wrote and co-wrote every song on but co-produced as well.
e) she actually cares a lot about her fans which other than Gaga and a few other to a milder extent, most celebs only say they care and don't back it up, Taytay doesn't charge for meet and greets all the time because her fans tend to go to her shows with their allowance, she has the T-Party room, a true Princess.
f) she does it all singing about princesses, dancing in the rain and fairytales
They can all stay mad tbh. Queen Taylor doesn't give a ****
