The Irish troubles were not a religious conflict.
The fighting was about home rule.
Sinn Fein makes no mention of religion in in its story of the struggle.

"On 14 April, Boko Haram stormed an all-girl secondary school in the village of Chibok, in Borno state, then packed the teenagers, who had been taking exams, on to lorries and disappeared into a remote area along the border with Cameroon.

The brazenness and brutality of the school attack shocked Nigerians, who have been growing accustomed to hearing about atrocities in an increasingly bloody five-year-old Islamist insurgency in the north.

"I abducted your girls. I will sell them in the market, by Allah," Boko Haram leader Abubakar Shekau said in the video, according to AFP, which is normally the first media outlet to get hold of Shekau's videos.

Boko Haram, now seen as the main security threat to Africa's leading energy producer, is growing bolder and extending its reach. The kidnapping occurred on the same day as a bomb blast, also blamed on Boko Haram, that killed 75 people on the edge of Abuja and marked the first attack on the capital in two years.

The militants, who say they are fighting to reinstate a medieval Islamic caliphate in northern Nigeria, repeated that bomb attack more than two weeks later in almost exactly the same spot, killing 19 people and wounding 34 in the suburb of Nyanya."
