One step at a time. The primary contradiction in Ireland is not the EU, it is the partition and British occupation of the north. Once this is solved a united Ireland can draw its own conclusions about the EU, which any honest appraisal of must conclude that it is a thoroughly neoliberal and imperialist institution, and like NATO a tool for Washington to control Europe and prevent any steps toward socialism or national sovereignty.

The whole thing with Brexit is that the UK is even more rabidly neoliberal than the EU. The tories did it because they thought that the EU had too many regulations, they literally rejected it because of the only good things it did (selfishly to its own first class citizens of course)

Now one could argue that the best scenario would be a socialist Ireland, but given their current position that could literally get them absolutely crushed. They would have to align with the emerging world order which would be a sufficient casus belli for most EU jerks

So yeah under this paradigm rejoining the EU is… let’s say, the institutional lesser stupid

Whatever rhetoric unifies Ireland is the right rhetoric

The desire for a united Ireland has been around for longer than the EU. It has nothing to do with the EU at all.
