Chris Dillow explains why he's still a Marxist. It's something I've also done: here and, more obliquely, here.
Chris gives 10 reasons why. Some of his overlap with some of mine. I won't review either set. I will only highlight the one of Chris's that I would vigorously dissent from:
Bourgeois ideas such as liberty, justice and the rule of law are partly empty fictions which the ruling class use only when it suits them.These ideas are not 'bourgeois', they are universal values, indispensable to any form of democracy that isn't a charade, and irreplaceable instruments of struggle for a better world. Chris's qualifier 'partly' on 'empty fictions' doesn't work: if they're only partly empty fictions then they aren't empty and therefore they aren't fictions. To continue to embrace as a reason for remaining (some kind of) a Marxist the very forms of dismissal of liberal rights and values that played so central a part in sending that tradition into brutality and totalitarianism is imprudent.
