And indeed apparently the line was in fact "say what you want about the tenets of national socialism", not "say what you will about the tenets of national socialism" (https://www.youtube.com/watch?v=b_29yvYpf4w).
In my experience racists tend to just latch on to different authorities to blindly follow and obedience and conformity are even more strongly enforced. I've had long discussions with racists over the "rebel" identity they see in the confederate flag who shortly after demonstrated incredible amounts of boot-licking when it came to police. Most of the racists I've meet were very dedicated to hierarchies, a select set of social norms, old-fashioned gender roles, etc. and conformance was absolutely seen as mandatory.
