Hutu reify the biological distinctions, generating a taller elite and a shorter underclass, but with little relation to the gene pools that had existed a few centuries ago. The social categories are thus real, but there is little if any detectable genetic differentiation between Hutu and Tutsi. Tishkoff et al. (2009) found their mixed Hutu and Tutsi samples from Rwanda to be predominately of Bantu origin, with minor gene flow from Afro-Asiatic communities (17.7% Afro-Asiatic genes found in the mixed Hutu/Tutsi population). Hutus speak Rwanda-Rundi as their native tongue, which is a member of the Bantu subgroup of the Niger–Congo language
Rwandan genocide government blocked "Inyenyeri News", "The Rwandan", and "Le Prophete." In a documentary, BBC mentioned that a significant number of Hutus were killed and discussed theories of the RPF shooting down the president's plane. In response to the documentary, the Rwandan government shut down BBC in the local to BBC promoting a "revisionist" position on the genocide in a documentary. While before the genocide, Rwandan history textbooks would acknowledge and highlight differences between Tutsi and Hutu people, today, the only government approved Rwandan history textbook stresses the Rwandans as one people and virtually ignore the ethnic differences and pre-genocide conflicts.
