In other words, people with horrible beliefs are the only reason why you can stand on a street corner and preach about socialism, communism, anarchy, etc.

Some famous free speech cases have involved protecting the expression of 'horrible beliefs' (to use your phrase) but to suggest that all free speech jurisprudence stems from those cases is simply not true.

Pornographers of various kinds have made more (and better) arguments in favor of free speech than any political actors I'm aware of, and to cite the KKK as the harbingers of free political expression is to ignore the significance of cases like Cohen v. California (from 1971) where a man convicted of disturbing the peace for wearing a jacket bearing the words 'Fuck the Draft'in a court house had his conviction overturned.

National Socialist Party of America v. Village of Skokie isn't so much a landmark case as the most recent one, and one that punts on the fundamental issues at that. Terminiello (including the dissents) is a far better template to work from.
