Judaism is not about having sympathy for the ugly, ignorant, cruel and stupid. Jews are required to hate their enemies. Africans are the enemies of Jews.
Judaism tells to love the simple innocent and ignorants. Are those tribes in Africa, who don't even have an alphabet, enemies of the Jews? Don't be silly! They may not even know who the Jews are, in fact they perhaps don't know any tribe outside themselves.
B"H I met a Rav firstly, otherwise I would have belived that Judaism is hate!
Go to Africa and then speak about it!
The Falashas, even more advaced than their native African neighbours were surprised when the Israelis informed them about a Israel. One 19 years old Falasha was amazed to know about electric lighting. He said " My father had told me once that there was life outside Ethiopya, but I didn't even know the name of any country". When the Israeli soldiers told him "we are Jews like you", He just didn't know what "Jew" meant. So the Israeli said "I believe in One G-d, as you do".
The only person I heard saying ignorants must be hated was a Pentecostal Minister's secretary. He said "ignorants and JEWS will burn in hell"
