one of the founding member of the Aryan Brotherhood is half jew, is proved by a tattoo on his chest with the Star of David.
The whole aryan nazi idealogy is just for recruitment once a person is in its just like every other gang drug dealing , prostitution, rape, murder etc etc.
There are probably a few guys that honestly believe that they are soldiers in a race war but apart from in the prison that really hasnt/isnt happened. Its just a criminal enterprise, and i think their alliance with the mexican mafia is both for business and for survival interests.
Besides you cant have a race war from a meth lab in a trailer park anyway.
