Whenever people bring up “anti-white racism” it’s almost always racism against minorities who happen to have white skin, who experience racism because of the former in spite of the latter, not the other way round. For example racism against Jewish people, people from Roma or Traveller background, and also prejudice and discrimination against Eastern European people.
It’s a horrible twisting of facts and is exploiting ethnic minorities’ struggle in order to defend racism.
Jews experience racism. Some Jews have white skin. This does not equate to “white people experience racism!” Jews suffer racism because they are Jewish, not because they are white. The reason racists target Jews is because racists and white supremacists DON’T consider Jews to be white. (Which isn’t even getting into how Beta, Mizrahi and Shephardic Jews are mistreated both internally and externally.)
There’s a whole long history of how “whiteness” is constructed and controlled and how systems of oppression dictate and control access to whiteness. Look at American and the “one drop” rule, look at the US Supreme Court hearing cases to determine whether someone is legally allowed to consider themselves white or not.
Obviously there’s a whole other element here regarding passing, passing privilege, and how colourism and racism intersect. I’m certainly not suggesting that the oppression faced by ethnic minorities who have white skin or who are white-passing is anything like the violence and abuse experienced by black people. But the circuitous argument that often comes up on these threads to pretend anti-white racism exists is not valid and is honestly so exploitative and hurtful.
