I write a regular column for Fourth World Eye, an e-zine published by the Center for World Indigenous Studies (the premier indigenous think tank in the world). I also have a dozen personal blogs where I write on a daily basis.
The following links probably provide all you need to see if I would be a good fit as a writer or guest speaker for your organization.
Issues: democracy, human rights, world indigenous movement
