PORTLAND, Ore. (KOIN) — A CBS News original that was broadcast online Monday took an in-depth look at racism in Portland from it’s founding to today.

“Portland | Race Against the Past” looks at a legacy of “white supremacy in Portland (which) is never far from the surface, and in reality, has never been that well hidden,” according to anthropologists and academics who have studied Portland’s history.

“It’s a great place to live even with all the problems we have,” Paul Knauls Sr., who was featured in the CBSN documentary, told KOIN 6 News.

Knauls has owned Geneva’s Barber Shop in Northeast Portland for more than 50 years and has seen much of the trouble highlighted in the documentary.

“Portland has had a long history of racism,” Knauls said. “You come to Oregon and you think it would be different but it’s just a real underlying something there that they feel they’re better than us.”

The documentary looks at the Ku Klux Klan and it’s booming membership in the 1920s, the devastating Vanport flood that wiped out the homes of tens of thousands of black families and the recent rallies in downtown Portland.

Despite what happens in Portland, Knauls is optimistic that the future will be a brighter one.

“I love Portland, I love the people of Portland and I think we just got to keep pushing to make sure everything does turn out OK for everyone,” he said.
