Some interesting conclusions from what is, and is not, said at an exhibition on the Rwandan genocide:
The texts accompanying the exhibits were not entirely satisfactory: but then perfection is not of this world. I found, for example, the strenuous denial of any physical differences whatsoever between the Tutsi and the Hutu, and the claim that the difference between the two groups was purely social in origin, not entirely convincing and in any case somewhat sinister in its implications. For it meant that, if there had indeed been genetic or physical differences between the groups, the genocide would have been in some way less serious, less abominable, than it was. But this is wrong: it matters, ethically, not a jot whether there was or was not a real biological difference between the Tutsi and the Hutu, or how great or small the genetic overlap between them is; for the simple fact is – it should hardly need pointing out – that it is wrong in any conceivable circumstances or for any reason whatever for people to massacre their neighbours in an attempt to wipe them out altogether: and this is so whether they are biologically indistinguishable or easily distinguished.
