"Northern Ireland needs a political system based on class and economic interests, rather than on community and identity."
That is a very revealing and interesting statement, which I strongly disagree with. What it advocates is a form of "social castration" and dehumanisation.
Yes, dehumanisation, because we evolved as an inherently and intensely tribal animal. Demonising and suppressing our tribal nature dehumanises us. We castrate animals to make them more manageable, which is exactly what the state seeks to do with its citizens.
Some would argue that the state needs to do this for its citizens own good and for the good of society at large, but this has never been the purpose of the state, even the democratic state. The primary purpose of the state has always been to facilitate society's SELF-exploitation to the personal advantage of its ruling elites and favoured (especially wealthy) clients, at the expense of society at large, ultimately leading to its self-destruction, which is why all past civilisations have declined and fallen.
It is no coincidence that we are culturalised to trivialise, ridicule or demonise our tribal nature, rather than giving it the serious attention and study that it deserves, because the state and capital are busy manipulating and exploiting it for their own purposes and don't want any light shone on what is going on.
