I don’t agree with this assertion because Boko Haram have different ideology with Almajiri system. In Islam there are different sect e. g Shi’a, Izala, Sufism etc. As a result of the division in teachings & other religious activities intra religious conflict occurred. Thus, Boko Haram ideology is parallel with that of Almajiri system. In fact among the Boko Haram members there were graduates (I happened to knew number of them during our campus life in the University) who tore their certificates on the belief that western education is a sin. The Boko Haram spiritual leader (Moh’d Yusuf) didn’t not study in Almajiri school but attended formal educational system.
Therefore, the root cause of violent extremism in the North East is far beyond Almajiri system of education.
