I consider myself a White nationalist because 1) I am white, and 2) I want the white race to survive. The last thing I want is to live in a world of negroes and other mud peoples. And I don't want my children to have to live surrounded by them, G-d forbid raped and murdered by them.
I also believe white Western European civilization has given much to the world. I do not want it to die out, or the people who inspired and created it. Basically I hold the same views on this issue as Rabbi Mayer Schiller of Skver.
I realize that some people confuse white nationalist and white supremacist. I do my best to explain and educate people as to the differences.
I realize that neonazis also often call themselves white nationalists. I refuse to let neonazis define who and what I am, and I also realize they don't regard Jews as white. I say, screw them, I will identify as white because I AM white, and if they don't like it they can kiss my tuchis.
I'm not the only White nationalist Jew I know. As Ashedina said, there are many on her blog, such as WhiteDevil and others. There are also Jewish WN's who have their own blogs, such as Nicholas Stix, jewamongyou, Lawrence Auster, Michael Levin (author of "Why Race Matters"), Michael Hart, Rabbi Mayer Schiller of the Skver Chasidim, and others.
