Littegrey, imagine if he had put something similar about black people - maybe a "bring back slavery" post or something. He'd be slated for it, but because it's about Irish it's ok 
mountford, I put some figures on the last thread. Firstly, NI had almost the lowest turnout, with only 2/3rds of the electorate voting, and of those over 55% voted to remain. So overall, only 28% of the electorate actively voted to leave. I suspect most of those were Unionists.
My figures might be wrong, but I think about 40% of the electorate of NI (at most about 350,000 voters) support the Unionists, in other words about 7% of the 46.5 million UK electorate are holding up Brexit. No wonder the British government doesn't give a shite about them.
