Yes, it is unreasonable. I am a visible minority, and am very offended when that factors in to hiring practices. It matters to me that my acceptance is legitimate and based on merit, and it tarnishes my reputation every day that others who do not meet the same standard are accepted (i.e. meet the threshold) merely due to their skin color.

Aside from that, whoever this "we" is that you're discussing, it does not include myself. You may have unconscious biases to people who are of the same race, etc., that's on you, and people on average may have such inclinations. However, you have cited no references indicating the universality of this phenomenon, nor do you possess any pertinent data on me. It would be more fair and correct to use "I" or "in general, people...".

The fact that you're a racist person is not in dispute here, we both agree. The question is whether you want to apply your prejudices in an affirmative or negative sense. My contention is that I prefer and believe it is ethically superior for hiring and acceptance practices to consciously remove, as much as possible, the influence of prejudice for each candidate.
