I think a lot of people are trying to change the world, but the ways in which they're trying to do it -- communes, squats, "temporary autonomous zones", free food projects, independent unions, and so forth -- are not much noticed or respected by the kind of leftists who inhabit academia and the media and generally dominate leftist discourse; these would rather talk about the big issues. They seem to be somewhat depressed by contact with bourgeois institutions, hence the confusion about the present war. (Although my perception is that the resistance is much more energetic than it was during the lead-in to Vietnam, and it _has_ prevented liberal imperialists from presenting a united front. That's a start.)
