For me the significance of this video includes:
1. Zinn is willing to support a place at the table for 9/11 truth advocates. He stated that as long as the conference has at least 22 presenters that we should be allowed to speak. Please contact me if you want to help make a list of such conferences and lobby for inclusion of our speakers. Big time left gatekeepers are likely to be less open minded than grassroots followers who would have no apologies to make. That is why we would go to these conferences.
2. Zinn asserts our case is too complicated. I urge us to discuss what single pieces of evidence standing alone are each sufficient to move us beyond whatever threshold we are seeking (real investigation, convictions, etc.)
3. All leftists should be susceptible to the argument that proof of inside job should undercut racist stereotypes of Muslim terrorists.
4. We should be able to find other major leftists who would agree to the importance of looking not just at civil liberties, but also resisting full blown police state with martial law. Truthers, leftists, and conservatives should be able to agree to work in coalition on this issue without getting bogged down in their disagreements.
