Dude, I grew up with the those cowardly shitbags killing innocent bystanders. Don't give me any rhetoric about them fighting any fucking revolutionary war. They lose all rights to be treated as human when, as an organisation, they intentionally set out to kill people as PR "for the cause".
It was well known at the time, and confirmed by Sinn Fein afterwards though never officially "proven", that a huge amount of money was sent from the USA to fund the IRA, it was called Noraid, and it funded them to the tune of millions of pounds. That was American *people* exercising their rights and freedoms to fund an organisation that murdered men, women and children indiscriminately.
The IRA are vermin, scumbags, the leprous weeping sores deep up the arsehole of humanity, and those who made their actions possible by funding them are no better. Just ask the parents of the murdered children how they feel...
