i studied a bit of the 1994 rwandan genocide in year 11 but i did it as for history. if your using the movie for english look up a it of the background becausee like the last person who wrote somethign said it was european influence, especially belgian that started identifying the groups. also maybe you could talk about the moderate hutus that didnt really belong to either group and were being slaughtered by hutus anyway, so they didnt belong to either group.
