Affirmative action is not only an example of failed attempts toward amending the previously wronged groups, but is also an unfair system of categorizing an individual.

I don't think so: affirmative action in any instance is unconstitutional and unfair. Even though it may attempt to amend the wrongs of previously wronged groups (which isn't the only instances of affirmative action), it fails while unfairly treating other groups--ie. Asian Americans.
