> Discriminating against an individual based on their race is a moral wrong
People pick partners based on race. Is that morally wrong?
> Our system of morality and justice operates on individuals, not groups.
What do you mean? Class actions don’t exist? Did I imagine the 19th amendment?
> people pick partners based on race. Is that morally wrong?
Wrong, but not illegal.
> What do you mean? Class actions don’t exist?
You can’t have class actions based on pre-existing groups (say, “Italians”). You have to define the group in a way that provides a high level of certainty that all class members were subject to the harm that’s the basis for the suit.
> People pick partners based on race. Is that morally wrong?
Depends on their reasoning. If it is that they are attracted to people with a particular physical appearance that correlates with race, then its not morally wrong. If you are doing so because they do not want to pick a partner who they believe is of an inferior race, that is morally wrong.
