I am...unclear on what you're actually arguing about. You went from arguing that white people are oppressed for being white and/or that white as a unified race wasn't the invention of racism to separate the white European ethnicities from black people, to straw-manning me to argue that white people were never oppressed the same way black people have been (and continue to be).

Both me and the OP are saying that the idea of a single "white" race was the invention of racists. To separate white Europeans from other people. Before the white supremacists coined the term white as a race, your race was French, Swedish, Irish, British, Russian, etc. White is just a label to lump all these Europeans from disparate cultural backgrounds who hated each other's guts together to form a unified front against "the savage black man" and "the Asian menace."

And nobody has ever been oppressed for being white. When was the last time you heard of somebody being passed over for a job because they were too white, or the cops going around arresting all the white people off the streets. White people probably suffer the same treatment as other foreigners in xenophobic countries, but they're not singled out for being white.
