Reconciling Republican Left and Other Socialist Views

My opinion is that the NI issue is that of one of class oppression and without going into too much details I have posted on why I believe such an issue exists. On the other hand, my fellow PW Republican users are of the opinion that such an issue is down to tribalism and imperialism by the British state of which they have provided ample evidence to assert their claim . With the two issues having such commonalities is it therefore sensible that we reconcile both the Republican left and the Trotskyist, Stalinist and other traditions that exist within a new left wing framework? Im not for one moment suggesting that we merge Republican and other left wing ideaologies but we look for common ground and work together. There has already been some work on a local level from such groups as Eirigi and the ULA and as such there are some links there. Sinn Fein and ULA have a lot of policies which are similar and the major difference is the view of NI and how the issue is dealt with. Could commonalities be found that could bring the different traditions of the left together to work as one force to counter the effects of current status quo and that of any new right wing party that emerges?
