Philosophy links to neither sexism or "The Demographics of Africa" (and while some older version might link to sexism, it seems unlikely that it ever linked to the Demographics of Africa"). Both of those do link to Philosophy, however.

Alternately it is directed, except when it doesn't find an easy route and uses an undirected result.

Click on "African People" in https://en.wikipedia.org/wiki/Philosophy#African_philosophy, you'll arrive at Demographics of Africa.

Likewise "Gender Bias" redirects to Sexism.
