I'm aware there are a few black Jews - apparently a vast throng of 750 in Uganda - if that was the point of the link.
No. Article was just coincidental.
The number does not depend on Jews. If more Blacks- or Asians- or Scots- converted, there would be more such Jews.
The point is that Judaism accepts all people. To assert it's ethnically based is nonsense.
I'd say that's more than a few.

The Ethiopian Jewish community was large. Sadly they were persecuted and many, many were killed. Tens of thousands did escape to Israel.
There are also black Jews in South Africa.
