"Thanks for the website of the Freedom of Religion Foundation. If you had said Freedom from Religion I would have been concerned."The person with the question had typed "Freedom of Religion Foundation" but provided the URL for the "Freedom from Religion Foundation" in her question.
The Freedom from Religion Foundation is a non-profit group dedicated to promoting church-state separation and educating the public on matters related to non-theism. This group's social justice work sounds like something that many Unitarian Universalists would support and affirm.
Are you suggesting that Unitarian Universalists should reverse their past social justice positions affirming church-state separation?
Are you suggesting that we should not support non-theism education when we know that non-theists are marginalized in our culture?
A 2006 University of Minnesota study reported that atheists are perceived as a group worthy of marginalization and exclusion by many Americans. They are viewed as the least-trustworthy group according to this survey.
I know the disputes within Unitarian Universalism over "language of reverence" and theological diversity can and often do get heated.
However, we do need to remember that our churches have a duty to "comfort the afflicted and afflict the comfortable" -- part of this duty may include finding a way to be welcoming to all and not excluding the non-theists in our congregations in order to improve our "marketability" in the religious marketplace.
