The UU Ferguson Response Team (local STL folks and others from around the country) has published a set of resources that may be useful to you.
Julie Taylor writes: "Having spoken and been in electronic communication with many UUs regarding what is happening here, I think there are many misconceptions going around. I believe the information in the media toolkit and messaging documents may be of use in talking to your congregations and in your communities, not just talking to the media. And I encourage everyone to get information from resources that are here, on the ground, rather than from the mainstream media. Even outlets such as CNN and MSNBC have been consistently wrong.
Please feel free to distribute these materials widely. And please see what you can do where you are to expose the institutionalized systems of white privilege and racism that are destroying our humanity."
