I dont think that is a fair equivalence. The mexican cartels dont do what they do in the name of Christianity. Boko Haram on the other hand, does kidnap and traffic kids and murder people in the name of Islam. From wikipedia
their main goal was to “purify”, meaning to spread Sunni Islam, and destroy Shia Islam in northern Nigeria"
On 14–15 April(2014), Boko Haram kidnapped 276 schoolgirls from Chibok, Borno. Shekau(Boko Haram’s leader) announced his intention of selling them into slavery.
Boko Haram is less of an issue nowadays and hopefully these kids are just kidnapped for ransom, but Boko Haram normalized this practice and still exists(and their allies).
