Pittsburgh Principles

The Pittsburgh Principles are the work of groups collaborating throughout the Pittsburgh area to script a document that outlines our solidarity with each other. The inspiration was derived from the the historic St. Paul Principles, and a growing number of groups are currently in the process of signing on and adopting them as pillar of their organizing. Please contact us if you would like to sign on and have your group listed below.

• Our solidarity will be based on respect for a political diversity within the struggle for social justice. As individuals and groups, we may choose to engage in a diversity of tactics and plans of action but are committed to treating each other with respect.
• We realize that debates and honest criticisms are necessary for political clarification and growth in our movements. But we also realize that our detractors will work to divide by inflaming and magnifying our tactical, strategic, personal, and political disagreements. For the purposes of political clarity, and mutual respect we will speak to our own political motivations and tactical choices and allow other groups and individuals to speak on their own behalf. We reject all forms of red-baiting, violence-baiting, and fear-mongering; and efforts to foster unnecessary divisions among our movements.
• As we plan our actions and tactics, we will take care to maintain appropriate separations of time and space between divergent tactics. We will commit to respecting each other’s organizing space and the tone and tactics they wish to utilize in that space.
• We oppose any state repression of dissent, including surveillance, infiltration, disruption and violence. We agree not to assist law enforcement actions against activists and others. We oppose proposals designed to cage protests into high-restricted “free speech zones.”
• We will work to promote a sense of respect for our shared community, our neighbors, and particularly poor and working class people in our community and their personal property.
