No, I am saying different measures should be taken instead.
What am I suggesting is that positive discrimination introduces a new mass injustice, affecting a great many people negatively. It may help some people, but it will treat many others unjustly. It would sacrifice lots of people who have not received any benefits from the injustice you want to reduce; it would be disregarding the fact that they are individual people, not members of a group having collective responsibility for the misdeeds of a group.
