Here's a link to a really fantastic Passover Seder Haggadah. to this non Jew anyway.
The new freedom Seder
"Prayer is meaningless unless it is subversive, unless it seeks to overthrow and to ruin the pyramids of callousness, hatred, opportunism, hatred, falsehoods. The liturgical movement must become a revolutionary movement, seeking to overthrow the forces that continue to destroy the promise, the hope, the vision." - Rabbi Abraham Joshua Heschel, 1970
