The issue with leftist unity is that many of these beliefs are incompatible both in concept and in practice. These groups have historically attacked eachother making it hard to see leftist unity as anything more than temporary partnerships. Alliances need to be handled on a case by case basis over what each side has to gain from working together. A person calling for blanket unity seems like they either don't appreciate the situation, or are trying to push an agenda.
