You really like to move the goalposts. But no, "the millions whipped out by the famines due to the incompetence, racism, and indifference of the British" is neither a "mass extermination", nor does it contradict my claim that most of Africa was taken without large-scale butchering, nor is it unparalleled by earlier empires (for example the Mongols in East Europe again, Rome in newly conquered Dacia). As for completely dehumanising enemies, as a way to differentiate from earlier empires, come on! "Barbarian" wasn't a word invented in the last five centuries, nor "slave".
