Injustices are subjective. Nazis would consider it a great injustice that we don't allow them to go around killing other minorities, or that we made Nazi parties illegal in the western world. What I'm getting at is that the OP statement can be bent to fit whatever ideology you want, and with that be able to get widespread support to "repress" minorities. It's not only "evil" people the ones repressing others.
