(Portland, OR)  --  A new series of billboards is bringing attention to the violent impact of racism on Portland's Black residents.  Artist Elijah Hasan tells the Oregonian that the billboards unveiled yesterday are aimed at connecting "the issue of Black-on-Black gun violence to the self-hate that is (created) by racism."  The billboards include phrases like "Destroy white supremacy, not each other" and "Racism plus self-hate equals gun violence."  Four billboards are currently up around the city, and three more are scheduled to be installed later this month.
