No one's been hacking each other to pieces in Zimbabwe; you must have that mixed up with some other country. Furthermore, the farmers have been defended by black Zimbabweans in the opposition party. Did you read the numerous postings about the elections in Zimbabwe this year as I recommended ? If not, please do.
The situation there is more complex than you want to make it, i.e. white people = good, black people = bad. The majority of the blacks voted against Mugabe in the elections, had their vote stolen by a corrupt regime, and are now coming to grips with that situation. Their quandary is how to formulate resistance in a region whose surrounding nations are turning a blind eye to the melt-down which is about to occur. Resistance requires assistance from some quarter; we had the French who assisted us in our War of Independence. Idi Amin was sent packing only when Tanzania invaded Uganda.
Please make informed posts, not just knee-jerk reactions based on what "everybody knows" about Africa amd Africans.
