You answer my question first.
Right. As you wish.
Intolerance of fascists, national socialists, and other friends of the OP, can take three forms.
One form is "I will snub them". I don't give a damn about that, and I know that isn't what we are talking about if we are quoting Popper.
Another form is "I will pass a law saying that certain ideas are not to be expressed" or "I will reuse to grant a permit for a rally simply because I don't like their ideology." That is probably what we are talking about, although all of the sudden you forgot that. In many European countries it is actually completely forbidden to be a Nazi, even though it is still allowed in the United States. They think our dedication to free speech and free exchange of ideas as some sort of support for those ideas, because they don't know what they are talking about.
