The nazis, or free speech and freedom of assmbly?

A Nazi's right to free speech and assembly, yes.

Nazis are people, and being a nazi is not a crime. Until they commit some sort of crime they should be afforded all the same basic human rights and freedoms as everyone else. That's just basic common sense.

And satanists. And homophobic churches. They used to know no point on the political compass and would defend all liberties.

Except anything second amendment (and a few others).

Everyone here keeps using that word, and I'm sitting here confused.

Can we sit down and define it, or are we to forever just throw it around as a convenient "bad people"?

In the case I expect the OP meant[1], it was the National Socialist Party of America, an explicitly neo-Nazi organization.
