I can’t find any statistics for what percentage of Northern Ireland is immigrants but I’d rather have 20% white immigrants than non whites 
Most immigrants I’ve met are poles or Eastern European Christians and they integrate well
Non white immigrants are absolute shit tier and make no effort to integrate. I went to school with a family of 6 Indians, they were low IQ, could barely speak English and stank of curry, they moved back to India because they got bullied.
