Why the UUA (USA)?
Whiteness, and chattel slavery (structural racism) were invented in the US, at the same time that modern Unitarianism and Universalism were being created.
Unitarians originally were largely from the New England European-American elite – often did not treat Native American peoples well, benefitted from slavery, and some were leaders in the Eugenics movement (promoting birth control for people of color because they were seen as inferior).
Some Unitarian and Universalist ministers (more Universalists, since Universalism was more of a working class movement) spoke out against slavery, but we did little as a denomination. After the Trayvon Martin verdict, many UU ministers said nothing in church.
UU’s did a very good job during the Civil Rights Movement, largely at the request of Dr. King, and we should be very proud of that.
In the late 60’s a promising movement (BAC, BUUC) was supported by the UUA, then de-funded because of a financial crisis, leading to a terrible conflict, after which many African-Americans left the UUA.
There was a long period of silence until the late 80’s and early 90’s, then excellent progress after that for a decade or so, but we have regressed, leading to the UUA President resigning over hiring inclusivity issues
