s Leutemann’s use of the term ‘semi-savage’ (halbwild – rather than semi-civilised) indicates, Neger in trousers were perceived as at best inauthentic, Africans corrupted by civilisation.
A central theme that I've picked up on throughout the German colonial period is hypocrisy. Germans wished to civilize populations, yet stripped different groups of their cultures, governmental structures, land, and more. The idea of Africans being corrupted by civilization (in this context) only furthers that notion to me.
