White supremacists consider Hispanics or Arabs as: brown.
Skin color as a determinate for being "white" and worthy of acceptance by some group. Hummm!! Brings a verse to mind. "Man looks at the outward appearance, but the Lord looks at the heart." - 1 Samuel 16:7
Tid-bit. Caucasian is sometimes equated with being "white". This is somewhat of a misnomer. Caucasian aka Europoid genes are found beyond northern Europe. I wonder if 'white supremacists' and 'black supremacists' use a color chart to determine a person's acceptability into their group? LOL!! /s
