Those who dislike Azealia will agree with you and those who stan for her will disagree. You really cannot have a rational debate here sis.
To answer your question, no. Was she rude to her? Yes. But you can't call it racism because of her micro-aggressions. Are white people getting lynched? Targeted and killed by police? Marginalised in every aspect of society?
I can understand that if you're white you may be offended, but understand that Azealia's statements has no real impact nor consequences on you nor Amethyst.
No...she is just J.E.A.L.O.U.S that some white girl from Australia is doing what she can't do. Which is get hit singles, and widespread notoriety! #endthread
