From the conference's description:
Religious fundamentalists have become a dominant voice in American politics—so much so that the word “religion” has become synonymous with the conservative political perspective. Because of this perception the progressive movement has been reluctant to embrace religion of any stripe, seeing it as counter to values such as compassion, freedom and trust.
Progressivism, in general, has not recognized the millions of Americans who possess a strong and vibrant faith that complements their progressive political views. The voices of these Americans have yet to be heard in significant numbers. The Spiritual Progressives conference is a step towards a remedy.
This is long overdue.
Part of the Rockridge Institute's work is in reframing the public debate. I am planning to lead a workshop at this year's NHC Summer Institute in which we will look at the ideas in George Lakoff's book Don't Think of An Elephant and brainstorm ways that progressive Jews can apply these ideas to intra-Jewish religious discourse (in addition to political discourse).
