So everyone walking with a torch in Germany is a Nazi...? You can find many images of people doing exactly that in Germany with a cursory internet search. The Nazis appropriated many existing symbols and customs, but that doesn't make the entire symbolism or custom automatically "Nazi". Neo-Nazis use Norse mythological symbols too. Other people just like Norse mythology. Context is everything, and the context here is most certainly not one of "a torch march protest". Not everyone who shaves their head is a Nazi skinhead either, nor is everyone who wears army boots.

I wasn't there. Maybe they were talking about the "final solution" for the Jews. I don't think they were, but there is no way for me to know for certain. But lacking any evidence of this, I find such a grave accusation based on such incredibly thin evidence – especially when stated like it's almost a certainty – deeply troubling.
