>>17825630 (OP)White nationalists don't need to believe that the white race has the highest average intelligence.
Look at Jared Taylor. He openly admits that ashkenazi Jews have an average IQ of 108-110, north east asians have an average IQ 105, and whites have an average IQ of 100.
The logic of white nationalism isn't that whites should stick together and stick up for each other because white people have the highest average IQ.
The logic of white nationalism is that white people should stick together and stick up for each other because
-white people are more genetically similar to each other than they are to non-white people and so it's better for their genetic evolutionary interests that they stick together and stick up for each other
-white people are a race and so have more similar, more compatible cultures with each other and more shared history than with other races
-every other race and ethnicity of people sticks together and sticks up for each other to pursue their shared interests and so white people will be at a comparative disadvantage and be taken advantage of if they extend colourblind , universal, individualist treatment to people when those non-white people don't do the same in return
BTW most white nationalists are ethno-nationalists in general and also believe that east asians should stick together and stick up for each other, that indians should stick together and stick up for each other etc.
So it's not like white nationalists believe that every race in the world should dedicate themselves to helping white people
They just believe that every race/ethnicity should stick together in their ancestral homelands and help pursue their race/ethnicity's shared interests together
