RhodesMustFall leader Ntokozo Qwabe, who demanded land from a white waitress instead of giving her a tip, remains defiant despite the public outcry.On Facebook yesterday he said white people, "supported by fellow non-whites", had started a petition to have his Rhodes scholarship to Oxford University withdrawn."White people have started another separate campaign to have me expelled from Oxford University," he posted.
