There is no negotiating with this ideology. They turned Europe into Sheol. Uproot them with prejudice. They will kill everyone who is not them once they reach critical mass.
Is throwing rotten eggs, tomatoes, and cabbages at them considered free speech? How about getting a tractor trailer towing a flatbed, and putting a band with big-ass speakers and a bunch of signs saying "Nazis are coward shitheels"?
At least two visible with performance "safety" props. Just need one squad fully armed to persuade them to disperse, one fireteam emplaced in front of their target of intimidation, other fireteam to hold a flanking position in skirmish positions behind cover but visible to ensure implicit awareness of being encircled and under-armed.
No need for provocative actions as such a counter-demonstration communicates clearly and calmly such actions won't be tolerated in these communities
I thought they were proud of their skin color, why the masks? Also, cameras can tell who you are by the way you walk (your gait.) Please start doing strange walks too, lol.
Id get my phone recording, ask them if they love the constitution, then when they say yes tell them I love the first amendment. Then id say "Fuck you!" and drive off.
Id do more if i could but id be outnumbered and they have guns so yeah.
