Do they though?
AFCON 2021 2-0 to N. Africans (Egypt against CIV and Cameroon, CIV is terrible at penalties so it is what it is)
AFCON 2019: 2-1 to N.Africans (Benin beat Morocco, Tunia beat Ghana, Algeria beat CIV)
AFCON 2017: 1-0 to N. African (Egpyt beat B.Faso)
AFCON 2006: 1-1 (Nigeria beat Tunisia, Egypt beat CIV in the final)
AFCON 2004: 1-0 to N. Africans (Tunisia beat Nigeria)
AFCON 2000: 1-0 to "Black African" (S.Africa beat Tunisia)
So in the past 20 years, of the 10 matches decided by PKs in the KO rounds, N. African teams have won 7 out of 10 times compared to Black African teams. Yeah that is appalling.
Even worse, CIV has lost 2 finals on PKs. One to Egypt then again to Zambia
