Guess we can still hope that DUers were there and haven't gotten to a computer yet to respond, or haven't seen your thread.
But in my experience, it's much easier to get DUers to "take action" at home on their computers than to get out and do anything. Especially when people of color are at the center.
See this threadI'm sad to say I was unable to get there myself, but when I do go out to protests organized by communities of color in my area, there are very few other white people there in support.
Thank you for posting. We have much work to do!
