Former Turkish DMOZ Editor Draws 10 Months In Jail
Please remember that the IRA that fought in the War of Independence is not the same organisation as the Provisional IRA that has conducted a terrorist campaign in Northern Ireland in recent years. So it's unfair to say that "the British government would have us think that your grandfather was a terrorist". Most people in the UK are fully aware of the appalling acts committed in our name in Ireland, and few (apart from a few rabid Unionists) would say that the Republican movement of the time didn't have a legitimate cause. The provos are an entirely different matter, and one shouldn't be confused with the other.
As for the "one man's terrorist is another's freedom fighter, others have done a better job than I could of that.
