They're calling themselves Nazis. They wave flags, with Swastikas.
I do understand that GWB wasn't a Nazi. And maybe there was a bit too much wolf-crying. But even if the boy has had this annoying habit at crying "wolf" every day–does that render you unable to recognise a wolf when he's staring you in the eyes?
Who is "they" in this sentence? The original comment was giving a hypothetical subject.
Someone waving a flag with a Swastika, non-ironically, yes, they're a Nazi. Someone calling themself a Nazi? Yes, they're a Nazi.
Holocaust-denier and notable anti-semite and crazy person David Icke? A delusional idiot, but not a nazi. KKK members who believed National Socialism was still socialism and battled Nazis in WWII? Racist fuckheads, but not Nazis. Francoist Faciscts? Probably not Nazis, although I'd forgive you for making a strong case for it.
We have words and phrases like white supremacist, anti-semite, racists, and Nazi. They all mean things, and there's plenty of overlap. I'm not sure what we gain by mislabelling one group as another, other than opening ourselves up to accusations we're crying wolf.
