All those cruelties you mention have been committed by Western (white) people to huge extents the past 200 years. Burning witches, genocides (e.g. read the history of the Kongo, the Maomao rebellion, war against native Americans, Australian Aborignes, etc.).
The links you quote: Would you think the Daily Mail and the BBC might have an interest to portrait Africans as savages during this second wave of (re)colonization that Africa is currently experienceing?
Dude, think first and travel a bit more. This helps to get rid of some serious prejudices.
