Should I refuse to be the beneficiary of racism or sexism?

When reviewing my job position file, I realized that my job could only be filled by a white female. I'd already planned to leave that job, but imagine that I'd planned to stay. In that case, what should I have done? Should I have left the job or protested in some fashion? (I was working outside the United States, in a country without any anti-discrimination laws.) Morally speaking, is the racism worse than the sexism?
