That was a pretty catastrophic attempt on your part.
Still, even the amount of people the 'RA killed; that's nothing compared to the potato famine, centuries of bloody oppression and the fighting it took just to get the free state.
And your book excerpt is shit, the troubles started in 68 as confirmed by that CAIN site if you'd bothered to check....
Look, you don't know about this conflict or the history of the British in Ireland. You don't even understand what you're defending. If you knew, you probably wouldn't bother.
I clicked back to the original web page because I want to see how long it claimed the Troubles extended.
To do that I had to make a table of the years vs the organization that did the killing.
The table ran from 1969 until 2001 (i.e., for 32 years) and the total deaths was 3532.
This is just over 110.37 killed per year. Of course this doesn't count the wounded or the number who's lives were ruined in some way. An example of lives being ruined is that austerity has created so much unemployment in Greece that a large percentage of its young adults have been forced to move somewhere else to get a job and support themselves. The likelyhood is that they will never move back to Greece. This is bad for Greece (whois going to be paying the taxes to support the retired people in 20 years?) and I don't think that being forced out of your homeland is good for the young adults either.
All these deaths are very much a bad thing, but who thinks it is comparable to an actual war?
I claimed that compared to an actual war that the Troubles were "minor". An actual war that only killed 110.37 per year (in grand total) is not much of a war. Of course, YMMV.
