I don't really think that calling to arms (in this case as self justice in combination with using Nazi symbols) is expression of free speech. It is totally okay that our understanding of free speech differs, but I just don't count that as free speech. And sympathizing with Nazis by using their symbols is not okay for me, too. I might be wrong, but in a lot of countries it might not be legal to call for self justice on a whole race.
