Yes, when you're Jewish and there's an armed mob of white supremacists on the street, the last thing we want to do is insult them by improper classification.
"Hey, are you guys totally committed to the 25-point program of the NSDAP or you guided more by Simmons' ABC of the Invsible Empire? I gotta make sure I check the right box."
I was curious, so I did a GIS for "capitol riot [nazi] flags" and was unable to find any pictures of people flying actual Nazi flags. There may have been more subtle things, like an article mentioned "stickers" but I didn't see anything I could identify. There was the guy with the "Auschwitz" shirt.
People did fly the Confederate flag though, so "white supremacists" seems beyond a reasonable doubt.
Yes, what I am doing is completely equivalent to actually forming an angry armed mob, and actually ransacking a building while chanting actual death threats against public officials.
It's absolutely ridiculous that anyone would argue that calling white supremacists "Nazis" is as bad as supporting the ideology of white supremacy. One is semantics and the other is a hateful fantasy that deserves no place in society.
