Well, considering that grelber believes that the "good old-fashioned...anti-Vietnam War" protests "had no real impact," perhaps his objection is based more on a perception that the occupiers' efforts are doomed to failure in the face of the unassailable hegemony of the ruling class (to wax Marxist for a moment
) and therefore represent a colossal waste of time, hence qualifying their practitioners for the "deluded, demented, morons" label. Ridicule based on the hopelessness rather than the unworthiness of their goals, as it were.
(For what it's worth, my take on the antiwar movement in the late sixties and early seventies is that it was a huge part of the process by which Americans' perceptions of that war turned negative. But that's from the perspective of one who majored in American History; perhaps the impact is less obvious to folks who aren't used to tracing the trajectories of historical movements...)
