I got myself in a little bit of trouble a few weeks back for expressing ideas like this, from Larry Alexander:

In general, blacks as a group are doing better than ever before materially. And for those who are not doing well, the cause is not the effects of slavery or Jim Crow. Nor is the cause racist bigotry, which, though some undoubtedly exists, is not a significant obstacle in blacks’ lives. Nor is it the vague culprit of “systemic racism.” …

The real impediment to the advancement of poor blacks – and everyone knows this, regardless of whether they admit it – is the cultural factors that have produced family disintegration, which in turn portends poor educational achievement, crime and poverty.

The guardians of the narrative are always on the lookout for heretics.
