"whiteness isnt real"
stand before any white man of any religion, offer him two choices:
you can choose to live in an all-christian nation, or an all-white nation, which do you pick?
white or whiteskin means racially white, genetically white, but not necessarily valuing it. White with capital W means racially conscious/nationalist/loyalist whiteskin. one is simple fact; the other is fact + political position built on that fact: whites who value being whites are Whites.
