text: There are 3 races. Caucasian, Mongoloid (Asian), and Negroid (Black). These are their scientific names. Anthropologically, they refer to relative frame size & shape of the head. Everything beyond that, including soft tissue, brain and other body systems, are exactly the same, just changes in melanin in the skin. They just look different because of environment.
  
  Mexicans are both Caucasian and Asian, as are most Central and South Americans. Many American Blacks are Caucasian and Black. Judaism is a religion, just like Christianity, Islam, Buddhism, Hinduism. If you're Jewish, there are ethnicities. It's just like being Italian or Irish.
  
  Askenazi, Sephardi, etc. If you're Ashkenazi, you are most likely at or within 2% of being 100% European, mostly living in colder climates. Being European, to most white supremacists, means white. So basically, I bet if they did a side by side study, you'd find most Ashkenazi Jews are as "white" if not "whiter" than most supposedly "white" supremacists.
