You likely won't agree with me, but I don't believe it's morally right to combat the effects of racism with what some these days call "positive discrimination." It creates a myriad of negative societal effects, from upsetting those who feel they're being discriminated against (i.e. some White men) and creating the impression (accurate or not) that the person given the position isn't competent. So, I do think there are negative consequences to doing this and I don't think they're worth it, as I don't think inserting people into top positions actually does all that much to hasten the process of integration. Yes, the appearance of diversity might inspire some, but if they too know the person was shoed-into the spot by a diversity effort, that effect will also be diluted. The reason Barrack Obama's win in 2008 was so inspiring and great was because it signaled to the rest of the African-American community that enough barriers had been broken down in society that this could happen. It was a sign of progress because Obama won the election the legitimate way. If he had somehow been ushered into the spot in some fashion that made it even just seem like he was given preferential treatment, it wouldn't have had the same effect.
