I grant that Colbert probably created the video with no intent to do conservatives any favors.
However, the inherit, undeniable truth of the situation - that the OWS protesters are a bizarre marxist hippy cult - utterly overwhelmed any original goals the segment may have had to bash the right.
Try not to overanalyze. The end result was a home-run for the right, and a disaster for the left.
Considering the intended audience—it ain’t The Right—I don’t see how it’s a homerun. Colbert’s cred with the college lefties is only secured by this.
