Yes, those people can credibly be labeled Nazis, but I assume roceasta is referring to the wider halo around them, of people also being labeled Nazis. For example, Trump was frequently labeled a Nazi for condeming violence, in his words, "on both sides. On both sides."

Which I found disturbing, but I don't see how it makes him a Nazi.

Why did you think it was disturbing, and what's your opinion on the theories the violence at Charlottesville was planned?

The police seems to have effected a policy that all but necessitated a violent confrontation, by forcing the alt-right protestors to move through a large hostile crowd of Antifa protestors on the way to their new location, and the police not protecting the alt-right protesters.

There's more strange things that happened that day, but was there any official explanation why the police officers were ordered to use these unusual and harmful tactics?

This is why people call Trump a Nazi.

That literally and metaphorically doesn't add up.

It suggests that he sympathises with Nazis, which is close enough to being a Nazi for most people.

Yes, because anyone who disagrees with Antifa's tactics should reasonably be assumed to be a Nazi sympathizer... I can't roll my eyes hard enough at this.

How on earth does it suggest that? If I say "Hitler was evil and Stalin was also evil" am I somehow sympathizing with Hitler?

Person, AFAICT there was just one guy with a Nazi flag but a lot of picture where made of him.

Portraying the whole alt-right (or the whole right) as Nazi's is inaccurate, offensive and divisive. It just helps them, and it leads to everyone reasonable getting stuck between angry fascist communists and angry fascist Nazi's.

As an aside, white supremacy != Nazism. Nazism includes white supremacy, but adds some other factors like fascism. White supremacy is not all that different from the popular Jewish supremacy movement in Israel. Most peoples want to preserve their cultures and not let themselves be replaced, but it seems like only European welfare states and the U.S. are ever attacked for it.

When did you last hear about the "Islamic supremacy" that is the dominant culture in the Middle East?
