What happened to trying to understand one another? Or should others only try to understand you, without you trying to understand them? The premise behind affirmative action is that it is needed in the present to correct for other forms of systemic bias that we haven't been able to eliminate yet. Practically all of the people who believe this, whether they do so rightly or wrongly, have color blindness as an eventual goal, just that pretending we're already there will never get us there. If you disagree with the premise, engage with it. Accusing others of arrogance etc. because you haven't tried to understand their POV - it's so well explained so many places that if you had tried you would have succeeded - isn't constructive.
