You can't turn back time and undo abuse. Trying to do so is just a waste of resources. In the race metaphor, the solution would be to just make sure everyone starts on a even footing in the next heat. In real life, I would say that means making sure all children have equal access to healthcare and education, regardless of their parents' income or circumstances. I don't see why race-based policies are necessary to achieve this.
Sure you can. The ancestors of those slaves are still suffering from that abuse. Your willful blindness is disgusting. The truth is that you are a racist. Only a racist would ignore all logic and pretend that the blacks of today are not a product of the slavery of yesterday. That the reason that they are poor and disadvantage compared to whites is because of the systematic oppression against them for hundreds of years. And the fact that many people agree with your comments shows that we are still infected with racism. Not as bad as before, but still going. You are proof of it.
And yes I'm angry, angry that racists people like you pretend that they are not racists.
If you define anyone who disagrees with you as a racist, I agree, the world will never be rid of racism.
So instead of affirmative action, radical income and property redistribution? I've never heard communism put forth as an alternative to affirmative action, but I'm all for it.
