Oh wait, the Klan is now Freedom Party's armed militants and considering that Fascists now being seen as the Friends of Jews...
Will KKK cease their discrimination against Jews and starts accepting Jewish membership?
Never. The Klan wanted to create a White Protestant Theocracy with no Jews, Catholics or Non-Whites amd that's final.
I believe that the American Fascists would become an entirely seperate entity opposing the Communists, Democrats, Republicans and Freedom Party/Klan. The Klan weren't even Fascist as well they were never Fascist, yes they were White Nationalist, but that didn't mean they were Fascist. I don't think the Klan would even care about the Jews, plus the Klan had also discriminated Italians.
Heck with Fascists being associated with Jews, I can't help but think they may end up supporting Civil Rights where American Fascism is a progressive ideology on the Far-Right Spectrum. Especially since you had Ezra Pound who was a Modern Artist and a Fascist despite Fascists often looking down on Modern Art. Plus I can see American Fascism be a mix of Italian Fascism (For Corporatism and its embrace on Futurism) and British Fascism (From Oswald Mosley and his BUF's unique policies) along with elements/policies on race from Brazilian Integralism (Brazilian Fascism which advocated for Racial Equality and Catholic Theocracy).
