I agree with you in your comment that point that these disguised insults against trump are inappropriate here (saying this more directly could have better effect imo). But please, you seems to be a good guy, do not fall into the Tribal trap, whether it is "i must defend m own even if i'm wrong" or "He has opinions from the opposite side, he must be wrong on everything else". The people this man hang out with AND this symbol he wore are enough evidences that he support, even if it is a little, Nazi ideology.
Since nowaday, nazi ideology has several sides, xenophobic, antisemitic, racist ant anti-feminist (i might forgot some), he might agree on at least one, and if you're dead set on defending him you can say he is only xenophobic or something, and the other part of neonazism, he doesn't support, but are you really believing that he wore this to say "i'm anti-communist"? If he did, he must have been seriously misinformed (and anyone this out of touch, honestly, deserve to be kicked of of any job that require you to understand history).
Please do not go tribal on Hn.
