Just my perspective on immigration in NI.
There are legitimate issues when unsavoury things are imported, knife culture of eastern Europeans being the one I'm accustomed to, and there is merit to those from here who are aghast by this.
And there is a legitimate issue when there is an influx of immigrants into a specific area which completely transforms it to the point it becomes unrecognisable (this applies to anywhere). What you want is controlled immigration in that those who arrive in a place adapt to it (it is afterall why they moved there) rather than have the place have to completely adapt to them. You do not want enclaves, basically no go areas, and areas where not a word of the native language is spoken. Immigrants should be able to come in, blend in with their new surroundings, abiding by its laws, whilst also retaining their own cultural heritage.
As I said I cannot comment on the merits of any genuine concerns those in Ballymena (or the other places where riots took place) have. The best thing I know of Ballymena is the advert "it's a big shopping centre in ballymena hi".
In terms of those who are just against immigration full stop, firstly I'd say it's a tiny minority who think like that here, but I'd say the vast majority who hold those views are staunch unionists as they view them as diluting the electorate, making a united Ireland much more of a possibility, or at least accelerating it.
Don't think there is any coincidence the riots (to my knowledge) are in unionist areas, albeit some nationalists have tagged along. It's the same community who partake in Orange marches, Ulster is British, and have kids burning effigys of the Pope in their giant bonfires. The Brits in Great Britain want nothing to do with these folk, and if they had a vote in the morning I'm in no doubt Brits in GB would vote to cut themselves off from here. I seen their bewilderment of here first hand when I went to uni in England. The Brits in GB view them as regressive and hugely embarrassing. As Kay Burley said to her viewing audience of Brits who knew nothing about the DUP in that Sky news piece, "who are these people"?
During PM questions, when the DUP man/woman gets up to speak the normally raucous house of commons chamber goes deathly silent, not out of respect or good manners, its because the other MPs from GB constituencies have nothing in common with the DUP man/woman who is speaking, they switch off and wait until they have said whatever they have to say, and then when they are done the noise in the commons reappears and normal proceedings recommence. Basically the speaker from NI in PMQs is seen as a break, an intermission.
Jim Allister, he epitomises the extreme backwardness of staunch unionists.
I view myself as largely neutral. Irish yes, but would in all likelihood vote to remain in the UK. But the staunch unionists who make things not work here are only making their nightmare more of a possibility. A NI that works is a place that people are not likely to vote for a change.
