Our system is based on equality of opportunity, not equality of outcome. If there are issues with the opportunity then we should work to fix those (like is already being done in inner cities cleaning up the drugs/pushing out gangs/preventing fatherless homes/etc). But pretending that you're going to fix those socioeconomic issues by giving preferential treatment to people based on race is just pulling other problems into the mix and is blatantly racist.
No one is advocating wishing anything away. If you want to focus specifically on equality of opportunity you can't do so without recognizing that race directly affects which opportunities are available to whom. Any solution that ignores that is just more of the same. And doing more of the same only extends the timeline of "when" that the original comment took issue with.
