The IRA killed about 1,000 British military personnel, 45 Loyalist Paramilitary personnel, 581 civilians, and few others (politicians, policemen etc etc). That's over a period of 35+ years, too (during The Troubles). These figures also include killings by splinter groups such as the OIRA (Original IRA), CIRA (Continuity IRA), RIRA (Real IRA) and probably others.
It must also be pointed out that the IRA never claimed responsibility for the Birmingham pub bombings, although it has always been attributed to them. This is how splinter groups came about, because the IRA's ideology was never about killing as many people as possible, because by killing innocents, it only damaged their cause. Their cause was purely political. Islamic extremists' cause is to please their bloodthirsty 'god' enough.
This is a lie. 'Conflict Archive on the Internet' broke down the numbers and during The Troubles, the IRA killed about 581 civilians. That is not the majority. The vast majority of the people the IRA killed were British military personnel.

Why are you so fucking incapable of understanding what I'm saying? The IRA, as a group, was not about killing as many people as possible. Some IRA members WERE okay with killing innocents which is why splinter groups came about. Do you understand what a 'splinter group' is?
