Do you view socialism/communist society as a reward for people like heaven is to Christians? 'cause it's not. It's a social necessity. You don't need to martyr yourself and no one in the actual-marxist movement is asking you to. Advancing the social dialectic is something that happens whether you want it to or not, so you might as well be pushing it in the better direction since there's no other option.
There Is No Alternative To Marxism.
