The list of large scale massacres in human history is endless and the Germans in Africa were hardly an exception.
It was exceptional within the context of its' time. Particulary the planning that was behind it.
"By "genocide" we mean the destruction of an ethnic group....
Which was precisely what the Germans intended. The orders issued made it very clear that the herero as an ethnic group were targeted, and made no difference between fighting men and others.
Germany had no plans whatsoever to eradicate the Herero from Earth, to make sure their language died out or their culture or whatever.
They actually did all of those things. As already pointed before, there was a concise plan to exterminate all herero they could their hands on. They later somewhat changed the plan by transfering some of them to labour camps, in which they were forbidden to use their language and a large part of them died. A lot of their cultural artifacts were also looted and brought to Germany. Again, I really suggest you read more about it. You are usually a very rational man, and I can only presume that you simply do not know what the Germans did there, or else you would not be claiming what you are claiming. In a way your reaction resembles that of many Germany, myself included, who first hear about it and have next to no knowledge about this. "Well yes, the Germans were brutal, but not genocidal." And after reading about it, most quickly change their opinion.
Why is it so hard for you to distinguish between a war crime and a genocide???
I could ask you why it is so difficult for you to accept the historical reality? The genocide commited against the herero was not one isolated act, commited in a short time span, but a concerted effort to wipe them out over a relatively long period of time.
A sad day if somebody working in an academic environ turns to be more like a preacher.
It is a sad day indeed when personal preference trump historical evidence. I am doing my best to correct this, but it is admittedly not a fruitful endeavour when other people either have no idea what they are talking about, or refuse it purely on ideological grounds.
