The SNP's majority and the remain vote in Scotland certainly give credence to that idea. Given how close the last referendum was the Brexit issue could easily be enough to tip the scales, granted it's always difficult to predict what other factors might be in play.

I must admit that part of me likes the irony of the UK "forging it's own path" resulting Westminster losing power and it's states gaining independence.

As a side note, I think it's better to refer to the northern Irish as republicans and unionists. The division is due to the partition of Ireland and not religious beliefs. The division lines might be the same but religious labels add irrelevant impactions. You don't have to be Catholic to be in favour of reunionification and vice versa.

The reason I spoke of Catholics and Protestants is because there is a religious background question ("what religion you were raised in") on the Northern Ireland Census, and it is widely expected to flip in this year's census, and if not this year, then almost surely by the next census in 2031.

By contrast, the Northern Ireland Census doesn't directly ask about whether one identifies as "republican/nationalist" or "unionist". The closest thing it comes to that is the question of whether one identifies as British, Irish, Northern Irish, or some combination of those three. But it isn't clear how exactly the answers to that question map to the community divide.

Religious background doesn't exactly map to community affiliation, but it mostly does. One thing to keep in mind is the distinction between small-u unionism (pragmatic support for the continuation of the status quo) and Big-U Unionism (support for traditional Unionist symbols such as the Orange Order parades, 12th of July celebrations, etc) – a decent percentage of Catholics support the former, very few (if any) Catholics support the later. Likewise, there are some Protestants who would vote for Irish reunification but very many of those would not want to associate with traditional nationalist community symbols.

I think, historically, the religious division did play a major role in the partition of Ireland in the early 1920s. Many unionists saw Unionism and Protestantism as going hand-in-hand. The Republican/Nationalist side placed less emphasis on religion – although the vast majority of Republicans/Nationalists were Catholics, there was a small Protestant minority among them. Now, as the decades have passed, with continuing secularisation, religion is less an issue than it used to be, but it still lurks in the background. The DUP was originally strongly linked to the Free Presbyterian Church, although the DUP has de-emphasised the religious linkage as time goes by. Their traditionalist moral stances (anti-abortion, anti-LGBT rights, etc) have even won them the support of the ultra-conservative end of Northern Irish Catholicism, but that's only about 2% of the electorate. Still more than the number of Protestants voting for Sinn Fein or SDLP.

In the context of the census that certainly makes sense and there are obviously strong links between religious backgrounds and political beliefs.

The reason I mention it is because I've encountered too many people in continental Europe who assume the Troubles were purely due differences in religious beliefs which seems absurd given how similar those two branches of catholicism are. I realize it's entirely based on my personal experience but I've seen it too often to ignore!

I agree that it is a complex situation, and that while religion is a major factor, it is not the only factor, and painting it as purely about religion is an oversimplification. On the other hand, I worry that many people oversimplify it in the other direction, and try to present it as if it has nothing to do with religion, which is false.

I think you mean Christianity, not Catholicism here.

Britain and Ireland have a long history of religious conflict and sectarianism. In recent decades, the intensity of that conflict has dropped down dramatically, in large part due to secularisation. But decades ago, it was much more intense.

That conflict was never primarily about religious doctrine, although religious doctrine still had a big role to play in it. A lot of it was about the fear that Catholicism was a means for foreign Catholic political powers – Spain, France, etc – to take over. It was also about who was the rightful king – Catholic King James VII and II was removed in a coup in 1688 and replaced with his Protestant daughter Mary and son-in-law William of Orange. James had an authoritarian ruling style, which caused a lot of conflicts with Parliament; but he was also an advocate of religious toleration, which was deeply unpopular with the majority of Protestants; those two factors combined led to his removal. James sought to regain the throne, and many Irish Catholics supported him, along with France. His supporters (the Jacobites) fought a war (with French help) to gain control of Ireland (the Williamite War of 1689 to 1691), but lost. (His supporters included some Protestants, especially conservatives who viewed the removal of the king in a coup as a threat to the legitimacy of the monarchy.) Protestant Unionists in Northern Ireland still celebrate their side's victories in that war to this day, particularly on the 12th of July.
