@Foxfyre,
Foxfyre, your argument is backwards.
Affirmative Action is not needed because of any failing in minorities (who you are calling "disadvantaged").
Affirmative Action is needed because there is still racism in the system.
The fact is that the majority of wealth, power and opportunity in the United States is in the hands of white people.
When we have an equal system, the wealth, power and opportunity will be spread equally (unless you want to explain why one race performs better than the others).
