The very identity of the left. I think there is an almost total disconnect between who the left tend to be (for example, people who took part in Occupy London tended to be those who could afford to take a few weeks off and are disconnected from labour struggles) and the arenas of industrial and labour struggle.
There is an unwillingness on the part of the left to move past a very outdated insistence on a reductive class analysis of society. This is probably related to my first point in that Marxism in particular is better suited today as an academic exercise because those who purport it come from ever smaller, ever less-proletarian and ever more-academic origins. It therefore seems that even within left struggles and movements, there is a disconnect between 'communists' who reduce their analyses and solutions to reductive class analysis and other groups whom communists seem unwilling to include in 'their' revolution.
I think the biggest problem for revolutionaries is to make radical politics more cohesive. Rather than this being some crass attempt to 'unite' the Leninists, Anarchists, Stalinists et al. under one shaky banner, I think this needs to follow a period of collective, critical evaluation of who we are, who we stand for, and what sort of society we want to live in. We need to show a more genuine desire to be a movement that unites broad swathes of society, and abandon the tendency to pay lip service to such desires, and scream 'identity politics' at any person/group that tries to gain a deeper appreciation of genuine unity. Unity of workers, women, black people and people of colour is not just desirable but it is the only way that we can oppose the monolithic social, cultural, economic, political and military hegemony that capital enjoys.
