Personally, I think there has been centuries of discrimination, oppression and trauma between Ireland/northern Ireland, going back to 1500s, even further when the Anglo saxons invade...awful unimaginable things have been done by the English/British government. Similar to how we are now reflecting on slavery, colonialism, race and imperialism, we should listen and learn and educate ourselves as to what has happened, there's no excuse for violence but it is understandable (not condoning anything), I'd like to see a ongoing conversation/debate perhaps similar to what happened in South Africa where people talk about what happened to them or what they did (truth) and worth through the pain and reconcile in someway? That way we would learn more as people have space to speak.
I'm doing a lot of family history ATM, and the attached photo came up, I never knew that King Henry declared himself lord/king of Ireland, took land away from the native people and gave it away to his lord's, protestants were settled in Ireland (plantation) to civilised the natives, land was stolen and given to protestants, in 1641 there was a rebellion to have the land resorted, in 1649 there was the Cromwellian conquest of Ireland, appalling atrocities commited by desperate people, then the English returned fire with fire.

Lots of Irish were very poor, the land they farmed (the left over land) was in poor condition (the good land given to protestants)they relied heavily on potatoes for food, when the crop failed, there was mass starvation, the British government adopted laissez faire (do nothing)... absolutely appalling.
I think there's a lot of intergenerational trauma..and no wonder
