You can be ideologically closer to faction X than to faction Y, but if faction X is the bigger obstacle right now to advancing the socialist cause then it is X you should be focusing on fighting, not Y.

Point being, as always with contentious issues there are contradicting forces "pulling" in opposite directions and every decision need to be taken in context and considering all the advantages/disadvantages, short-term and long-term
