All terrorism is bad. Including both sides of the NI debate, the ANC and Apartheid government of South Africa, Hamas and the IDF all of which have deliberately targeted civilians.
But although the IRA did kill civilians, this generally wasn't their goal and they took steps to actively prevent that. Re: Eniskillen, read your link. Neither you nor I know the truth. Re: Harrods, acknowledged.
Kidnappings and murders in Ireland and NI were done on both sides, the IRA disarmed when the RUC, a British state run organization that also collaborated with terrorist paramilitaries was disbanded.
As I said, nothing was done without warning. PIRA gave more then a half hour warning before bombing Harrod's despite three civilians killed. Enniskillen was aimed at a patrol of troops.
As I said, the Volunteers did not set bombs to kill civilians, warnings were given ahead of time. A very benevolent attitude I think against an enemy which invaded their country, flooded the north part with settlers, and whose army was shooting civilians in the street when Enniskillen and Harrod's happened. If England doesn't want to be in a war, the solution is simple - remove English troops from Ireland.
Odd that you mention Enniskillen, where they murdered 10 civilians, one police and no military personnel and injured 63 more and issued no warning. "Aimed at a patrol of troops" is a lie.
Take your biased ignorance elsewhere please.
