Covered. Caucasian, in context, is not a synonym for White.
When a White Nationalist is writing using the word White, it means "of predominantly European descent, without any more than trace Jewish ancestry or other obvious or large admixture from others".
Different words have different shades of meaning, and different groups can use the same word, with different shades of meaning.
i.e. a Black can say something is "turn't up" and I can say nothing was turned at all. Or I can understand that the Negro is saying "that is cool" when translated into my own language.
You do have a word or word sequence that you can use to differentiate Whites minus Jews, from Whites inclusive of Jews right? To refer to the X-Jews group alone?
So that is the definition of White, in context of how we use the word, like turn't up is for others.
In either case, the reality remains, that Jews and Whites who are not Jews, are genetically, culturally, ancestrally (etc etc etc) distinct. That is, they can be physically, in the real world, differentiated.
A Jew when they are criticising Whites also, understands they are not referring to Jews. As does a White Nationalist.
If dealing with language as it is is too difficult for your little brain, you can sub in Aryan, White Aryan, Person of Light, or Amalek when you see a White Nationalist use the word White.
Then, you can clear up the (feigned) confusion that exists in your mind only.
