The average Christian white nationalist has more in common, culturally, with a Muslim immigrant from the Middle East than with a staunch atheist like myself. But I would probably be welcomed in a "white nation" because of my appearance. If we're being very generous, white nationalism is intellectually lazy since it uses superficial traits like skin color as shorthand for culture/lifestyle when the two are, at best, loosely connected. But I think it's extremely naive to look at the history of white nationalist ideas and assume that superiority/inferiority is not implicit in the ideology.
