It would be a mistake to assume that those who have been oppressed historically whether that be through their ethnicity, their social disadvantage, their intelligence deficit, or just some accident of birth, it would be a mistake to assume these people are somehow, as a consequence, morally enhanced.

They are just as likely to be the opposite. Were they in a position to be the oppressors they would be just as bad and liable to behave in just as immoral a way.

Morality is about what you do and not what happens to you.
