I was bemused by this and have been digesting the reply I received from mumsnet hq for a few months. I politely suggested there could be different sections in Craicnet for NI and ROI. Not for any nefarious reasons, just because obviously they are two different places and someone starting a thread about moving to NI isn't looking for loads of responses from ROI people going 'well, I don't know about NI, but in ROI...'
For clarity, I am Irish in the Republic of Ireland. I received one of the coldest and snippiest replies that I've ever received. They told me they are not going to 'partition' Craicnet. I'm not upset but I am slightly taken aback and amused. Partition already happened 100 years ago and I was not personally responsible. Did I make a dreadful faux pas? Confused.
