can somebody explain the Beyoncé hate?

Abby
So I heard Beyoncé song at the CMAs with the Dixie chicks and all I see on my fb is how Beyoncé ruined the show and she shouldn't have been there cuz she's not country and how shes basicly a trashy rasict police hating whore and country people don't want a rasict police hater at there show 🙄 
First off I love the Dixie chicks but let me be honest the have a hand full of good songs 
While Beyoncé has tons of good songs 
   Second off didn't justin timberlake perform there and I also heard nelly did to so why is Beyoncé getting hated on?
