I have been taking a class on racism. The most helpful definition I have heard is that racism is not what or who you are, it is the outcome of your actions. This is great! It puts the conversation into an area of actions that are measurable. There is no speculation about who or what people are with regard to racism. All that matters is outcome.
True, I suppose. Actions matter more than words. And yet, words harm. So perhaps there is a both/and.
Why racism on Sabbath? One of the things that Rabbis encourage us to do on Sabbath is to set aside consumption and do things like read, learn, be joyful! Sabbath is also directly juxtaposed with the justice movement as the command to practice Sabbath comes on the heals of leaving slavery behind and moving towards abundant life. The Ancient Israelites knew a thing or two about diaspora (being forced out of their homes), justice, and rest.
So today, learn! Put your Sabbath to good use and learn how #blacklivesmatter began. Learn what it means when #blacklivesmatter is coopted with #alllivesmatter. Most of all, learn to be an ally to someone whose voice is not being heard.
