Questions about the war in 71

IMdB is not a site for factual, historical & political info.
That's like learning about Roman history by asking questions on "Gladiator" board!

The Northern Ireland question is way too involved and complicated to explain on this board ; it is not, was not, an easily explained good vs bad situation.
British troops were initially welcomed by the RC section of the population as they were seen as offering more protection ; this perception changed as it was overwhelmingly the RC population and Irish Nationalists who saw British troops (albeit on British Territory)as "occupiers"!

As I said, if you want to know the intricacies of these Troubles I suggest you look at many other better sites across the Internet, far,far more informative than this one, and more likely to be accurate too.

That the people there can dictate to the other 59,000,000 people in Britain proves the point

Northan Ireland most certainly IS part of the UK. The UK consists of England, Wales, Scotland and N.I.All of them are represented in the U.k Houses of Parliament in Westminster, London.No one section can 'dictate'to any other section.They all have their own governing bodies as well,for their internal affairs.Ireland,as a whole, was part of the UK until they voted,in a referendum,to leave the Union.But the six counties in the north of Ireland voted to remain in the Union as British.Therein lies the root of 'The Troubles'. The south of Ireland is a republic. The Irish Republican Army-an illegal organisation-set about 'persuading'the protestants in the north to join the Republic,for a united Ireland.Murder and mayhem were taking place,and as the north is British it became necessary for the British Army to become involved.That,Sir,is it, in a 'nutshell'.
I am afraid the remainder of your post makes no sense at all!!As you know,Scotland voted to remain British-in the Union. England and Wales certainly are not disenfranchised, as you put it.

Exactly! So if my brain needs to work it out, then that means the answers cannot be found on Google.
By the way, I've been reading many reviews and plot summaries of '71. They mention items such as "the doctor and his daughter who save Hook were Catholics..."
At no time in the movie did they say they were Catholics. How are we supposed to know? Brains cannot work things out when the director gives us no information. That's why we ask questions on imdb.
