I wonder if the silence about the war in Sudan, is not an instance of a different form for racism than anti-semitism, which I agree probably fuels some of the "newsworthyness " of the conflict in Gaza.
Looking back, no-one has bothered very much about reporting conflicts, disasters etc. in Africa during my lifetime, and I will be 74 this year.
I suspect that the real reason is racism - as in "black people do not matter, they are less civilized than WE are".
I do not hold this opinion - all the Africans I have every met have been good, kind, cultured people, and the various dictators and war-lords that have plagued the African continent in the 20th century were, in my opinion, neither better nor worse that Hitler, Mussolini, Stalin and various others Europe can with shame confess to having fostered.
But I fear it is a factor when we are not bombared with news from Africa, either when it is bad, as in Sudan right now, or good in the many countries of Africa that are doing well.
