I think you're generalising there, especially as we're still on episode one and that didn't provide any real details on the Northern Ireland Civil Rights Association.
What I have said in previous posts is that a raft of reforms was carried out in 1968 and 1969.
See attached images.
But at the same time none of these is what Provisional Sinn Féin and Provisional IRA were fighting for. As Professor Liam Kennedy, Irish historian from Tipperary and Economic Historian at Queen's University of Belfast stated:
"Many of the key reforms in housing, local government and voting had been conceded by the time PIRA went on the offensive. The remarkable record of the success of the civil rights movement showed the potential for further reform. But the new game in town was not reform."
The success of NICRA at reform of Northern Ireland threatened to seriously destroy the PIRAs plans for murder. So they went on the offensive as the historical record shows. John Hume made it clear that the Provisionals were oppressing the Catholic population as well as the Protestant population:
"We are under no illusions about that (PSF/PIRA) campaign. We are under no illusions that it had no mandate from anybody to get into that campaign. Neither are we under any illusions that if it has victory it will seek no mandate for anything else and that it will impose a dictatorship on the people. So, do not let anybody think that we do not oppose the work of the Provisional I.R.A."
- John Hume 1973
And Hume again:
"....all the major grievances today within the Nationalist community are direct consequences of the IRA campaign: the presence of troops on our streets, the harassment and searching of young people, widespread house searches, prisons full of young people, lengthening dole queues leading to the emigration of many of our young people, checkpoints, emergency legislation ... If the campaign were to cease, these grievances would disappear.
The troops would very soon be off our streets; they wouldn’t be harassing young people or searching houses.
Checkpoints would vanish, emergency legislation would be unnecessary."
According* *to Hume, the Catholic population absolutely rejected Provisional Sinn Féin and Provisional IRA:
"...the reaction of that community (Catholic), having suffered so much, was to reject every single candidate who stood before it in the Assembly election without the slightest trace of sympathy for any organisation which supported violence in any shape or form."
- John Hume 1973
For their part, the Northern Ireland Civil Rights Association flat out condemned the Provos. See the attached image from NICRA in 1978 taken from the CAIN website. The Northern Ireland Civil Rights Association blamed the Provisionals for a worse situation in regards to rights than existed before.
All of that and we've not mentioned the Republic of Ireland!
Do you accept that nationalists who didn't pay rates couldn't vote in the Republic's local council elections either?
When it came to One Man One Vote, Northern Ireland was lagging behind Great Britain, but actually ahead of the Republic of Ireland.
"The main area of contention was local government, where, like the Republic in the same period (though unlike the rest of the UK since 1945), rate-payers had votes calculated according to their property."
From the Republic of Ireland's Minister of State At The Department Of The Environment in 1977:
"A major undertaking of the Government's pre-election manifesto was that from January 1978 rates would be abolished on domestic property..."
As John Dorney pointed out:
"Rates and their link of the vote in local elections to property were abolished in 1977 but this also meant that local government was even more dependent now on central government funding."
A fact not included in the episode or mentioned by anyone here for a comparative example in relation to Northern Ireland.
I'm sure you will agree that none of this justifies in any way the terrorist campaign of the IRA.
