They are not necessarily "Nazis"... they are Christian, but the branch of Christianity they practice promotes White supremacy... there is a name for it. I forgot what it was, but I read up on it a long time ago. There is one of these racial Christian churches that gives out monkeys to all the church goers basically to demean Black people.
It is tricky really... a rare amount of people are actually full blown nazis. They are usually more affiliated with the KKK then anything else.
