Blacks are the most supportive of abortion legality in most or all cases of any race other than Asians, so that's one issue that isn't race that Blacks lean to the left on.

The other issues, yeah, you're right. I don't really consider taxes a social issue, but I realized I forgot about gun control.
As I point out, with a source, in another subthread, Blacks are more supportive of abortion than the nation as a whole, and second only to Asians. https://news.ycombinator.com/item?id=23936024
Even in your ancient (5 years after Roe!) piece, while Blacks were less supportive of abortion than average, they were also becoming supportive more rapidly than other groups. 40+ years later, that faster change has flipped the starting positions.
