Sorry, but I take offense at this "it is all a matter of opinion and all opinions are equally valid" BS. 1) It is trivially true that if you define your measure right, you can make anyone succeed. For example black people are better at looking like black people. But we try to define "stuff" in a way that correlates with ability to do economically useful tasks. There are excellent reasons to do so. 2) You are ignoring…
Your tone seems disagreeing, but I think your second to last paragraph is making the same point I’m making? I agree with you that it’s not fair, I’m just acknowledging that the adjudication of fairness happens outside the reach of science. It’s a matter of values not evidence.
But the others contradict most of what you said. The pro-affirmative action position that you outlined requires willful blindness and stupidity to accept. It is very emphatically not equally valid to the alternatives.
There may be better arguments for accepting affirmative action as valid. But that one is terrible.
