If you think Seattle’s race relations are on the same level or even close to any red state then I sincerely doubt you’ve ever left Seattle or been to a red state.
There are racist people literally everywhere but not everywhere makes a culture out of being racist.
I traveled all over Oregon and Washington after living in the southeast.
What you say holds true but to a lesser degree than true red areas.
A lot of the people who consider themselves conservative would be relentlessly bullied for being a liberal if they moved to an actual red area.
It’s funny because their utopian views of conservative areas mirrored my utopian view of Seattle when I lived in a conservative shit hole.
