I really think it is meaningless to speculate. There will be more elections, and things will change, and change again after that. If you zoom out and look 50 years back, wow! I live in a hugely unionist area (think almost no Catholics), and can certainly vouch for their being many "good" and "reasonable" people active in the DUP, who do good work at a community level.
However, when you look at the broader electoral area there are serious social problems with lack of job opportunities, poor education, intergenerational unemployment, drugs and all the associated ills. These problems are not unique to our area, but these need to be a priority. From a farming background originally, I'm also very concerned about the future and security of support schemes there.
Personally I don't know people in SF, but I've always associated them with support of the IRA. Of course, I'd also know DUP supporters very much aligned with our own wee terrorist organisations too.
There is so much opportunity in the wonderful part of the world, I hope we can take it.
