I doubt that all of them are Nazis. The guy in the leather coat certainly has a Hitler fetish though. His twitter handle ends with 1889 (which is Hitlers birth year), he's been photographed doing Nazi salutes at significant Nazi sites, his son has disowned him over the whole Nazi thing (before all this kicked off)...
I'm always a bit suspicious who use re-enactment as an excuse to wear the swastika. And remember this wasn't a re-enactment event, it was a 1940s day for that area. There were never any German troops in Norfolk in the 40s.
yeah, your arguments are sound and i know from personal experience that these groups of ww2 aficionados always have the odd or two Hitler fanboys.
my point is, even if the guy masturbates to nazi propaganda, i bet my money he stops at the fetishism. i've known footballs fans that are more dangerous, and i mean that.
now, on the other hand, neo-nazis in non-historical gear, with names like MARTYRS OF FREEDOM or whatnot, i find those much more dangerous.
still, i think we can all agree, if the guy is just a reenactor, a quick poke through his affairs wouldnt hurt anyone.
