What's your opinion then on such white identity speeches like the Confederate Corner Stone speech, delivered by the Vice President of the Confederacy?

"Our new government is founded upon exactly the opposite idea; its foundations are laid, its corner- stone rests, upon the great truth that the negro is not equal to the white man; that slavery subordination to the superior race is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth."
It seems that even a century earlier than your 1950's monoculture, the white people of America were not just calling themselves white, but in fact, were creating political philosophy centered around their white identity.
Not their polish, German, Irish, Finnish identity.
Their WHITE identity.
