Let's clarify a few things first:
"white" nationalism is nationalism for those with the genetics of white skin
Jewish "nationalism" describes Jews as a religion to stick with Jews.
Genetics is something one is born with. To say one is genetically "inferior" or "superior" because of skin color, eye color, hair color is true racism. There is no superiority in any genetics. Only physical attraction and nothing more.
Judaism is NOT a race. It is a religion/culture. Someone who is truely Jewish has a Jewish mother and can be any genetics..Tall, short, skinny, fat, blue eye, brown eye, black hair, blonde hair, negroid, caucesoid, mongoloid...A Jew is a Jew. And if someone truely wants to convert and do it properly, it doesn't matter what background they came from racially or genetically or even culturally.
So to sum it up. StørmFrønt is a racist white nationalistic nazi KKK movement. THey are racists of the worst kind..Just as bad as the Black Panthers et al.
As far as Jews marrying Jews...that's what our religion prescribes. It's not for genetic reasons..it's for religious reasons and cultural reasons.
If a white person wants to marry another white person of the same religion and doesn't prefer a black person, it doesn't make him a racist. It might simply mean that he's attracted to white skin and not black skin...big deal. But if someone says, "I won't marry a black person because they are racially inferior," then that's racism. If someone says, "i don't want to marry a black person because I disagree with African/Black American culture," that's not racism.
JTF is a movement which judges solely on what it considers evil behavior, evil culture, evil religion, and evil ideology irregardless of the race of the person.
