SK:
I think you need to actually do something other than be an anti-Jewish (which is different from anti-semitic) bigot to be called a Nazi.

For example..say..advocate putting them in ovens or at least endorse a pogrom or something. You can call Ratko Mladic a Nazi or maybe Tom Metzger.

However, some assclown who whacks off to pictures of RP and blames Jews for him not being successful (instead of his actual positions..which are often poorly thought out and articulated) does not rise to that particular designation.

As a native of Nuremberg, most of my babysitters were former party members.

There is indeed a difference between “I don’t like/trust those people” and “The Holocaust never happened and anyway they deserved it”. I have actually been present for conversations that involved the latter.
