>prejudice, discrimination, or antagonism directed against someone of a different race based on the belief that one's own race is superior.
Of course superior is an objective word, but I don't see any evidence in that quoted statement where she felt superior. Honestly sounded more like self pity, jealousy and stereotyping. "Those union people get paid way more than they deserve," "Those college kids get all the breaks." The only difference is her target were "brown and and black people."
She satisfied the first half of the definition, "prejudice, discrimination, or antagonism directed against someone of a different race" but I didn't see the second half, "based on the belief that one's own race is superior."
I could be wrong.
