You could start by not downplaying it as insignificant and offering up a bunch of excuses.
Even if a party disavows Nazis in public, if Nazis *still support them* - look at them and say "Hey, these are our guys" - then guess what?
Maybe the U.S.'s one-dimensional politics makes it clerer: Trump can claim he doesn't like Nazis, but so long as he serves their goals and Nazis themselves are on his side, functionally there is NO DIFFERENCE.
