English Jon,What do you mean politicians think your opinion is insignficant? Why do you suppose they spend so much time and money with polling ordinary people to find out what they think?
I'd say the biggest impediment of the British government effectively devolving in NI is citizens like yourself who spend all your time badmouthing the supposedly "violent" Irish, and insisting there is nothing to be done.
It's people like you, with your bigotry and apathy, who keep terrorists in business, murdering innocent children.
