This GE will determine whether the UK has a 'hard' or 'soft' Brexit.
A hard Brexit will mean we leave the common travel and trade area. This will have enormous implications for N Ireland. A hard Brexit makes it harder to avoid a hard border between NI and RoI which could have a real impact on the actions of dissident republicans. It also makes a border poll more likely putting the UK at risk of disintegration for both NI and Scotland. A hard Brexit will also affect N Ireland trade more significantly than other areas meaning the need for even more subsidies from the rest of the U.K.
Whilst I am aware that people will vote according to their own priorities AIBU to ask UK voters outside NI to consider the affects on one of the 4 nations of the U.K.
