Since I first was exposed to EarthFirst! in 1998, I have encountered people advocating for the idea of Cascadia seceding as a bioregion (WA,OR,N.Cali), from the United States.
Now I am fully aware that no seceding will actually occur from these conversations, and that beneficial side impacts such as increased community building and vision development may occur among members of the predominately white left in Portland.
That said I would highly reccommend that people committed to racial justice, especially white activists, check out "Ecotopia":
This book, while written in 1975 laid the foundation for much of the discourse that happens on the white left for seceding. In a patriarical, environmentally friendly, racist (all characters are white) book the author spells out a vision for a white leftist utopia which still haunts our conversations.
I am sincerely not trying to imply that anyone involved in the Cascadia seceding conversations is mal-intentioned. I just want to make explicit a history in our region which should be carefully considered, since it is so rarely cited.
Oregon gained its statehood during a time in the US when slavery was in great contention. As a territory comprised of mostly white poor and working class southern migrants there was great hostility toward the african slaves among the population of Oregon. As working people they had been forced to compete with the free labor of those held in slavery, and as white people they had been taught to fear and hate Black people, and really all people of color. Oregon became a state that did not have slavery, but *outlawed* the presence of Black people in the state as well. Till this day Oregon has a tiny Black population (something like 80% of all people of African descent in Oregon live in the Portland area). This is a direct result of structural racism, stemming from our nation and region's foundation in a slave economy.
While I always enjoy and value the political visions of commrades and friends, I do sorta wish that the energy put into this seceding debate/planning would instead be put into racial and economic justice work in Portland, there is so much to be done. Planning a secession movement seems more like brain candy than true ally work.
