Which group was not a target for fascism in the United States during world war II?

Fascism in general is characterised by a purist ideology (i. e., the ideology that a 'pure' national race is to be maintained within a country and that other races are to be eliminated). American fascism was no exception: it mainly promoted the rights of white Americans - which is thus a group they did not attack. For this reason American fascists are sometimes called "white supremacists".
