Our friend Marc Moscato sent along this link to an interesting story/conversation unfolding around a attempt to combat perceived racism through street art in Portland, OR. The story centers around a street art action where artists/activists temporarily replaced images of Confederate flags on a mattress store with images of Martin Luther King, Jr. The action was blogged about on the Portland Mercury website, and although the art is interesting, the responses to it are whats really worth checking out. A fascinating, rambling road through varying opinions on street art, vandalism, gentrification, class, yuppies, and property values.
