You're probably not aware fnovd, then many of the attendees were themselves Jewish, including those of 'Heiling' fame.

These people are trolling. This is classic trolling. They know this causes people to react and how the media works. For instance The Atlantic in their video on the NPI conference showed apparently 'dozens' of people doing the 'Heil' salute, but if you examine the footage closely you'll notice Richard Spencer is in fact holding up a water glass in one hand and the camera is being positioned multiple times in such a way to make the same three people look like six or nine people. There are classic camera tricks in that video actually to form your opinion (e.g. selective blurring), I'm sure you'll see them too if you go and look.
This is also trolling with a purpose in order to attract the right enemies.
As I said, this is not the high moral ground. Nonetheless they are not Nazis. You'll need more than some Jewish boys and an Asian pornstar for that to have merit.
This absolutely false. The word "zombie" is what people go to when they think of a mindless being. The word "golem" is what a nazi would say as a dogwhistle to let people know he's down with hating (((Jews))).
We Jews said we would never forget, and we haven't.
