There is no difference in the sense that if you can root out the act of discrimination and prejudice here in this instance then you can root it out in other instances (racial discrimination, sexual orientation discrimination) because as others point out they all have the same cause: prejudicial biases based on immutable (and irrelevant to whatever is causing the bias) characteristics. This is in essence why MLK said that injustice anywhere is a threat to justice everywhere, because injustice is all the same. We don’t fight racism just because we owe black people. We fight it because it’s fundamentally wrong, and not because black people just happened to have suffered a lot.
