Calling nazi rallies free speech rallies is Orwellian horseshit.

A Facebook page linked to the Boston event identifies participants as a “coalition of libertarians, progressives, conservatives, and independents and we welcome all individuals and organizations from any political affiliations that are willing to peaceably engage in open dialogue about the threats to, and importance of, free speech and civil liberties.”
Some of the same groups organized a similar event on the Common in May, where there were two arrests.
One organizer, John Medlar, a student at Fitchburg State University, told WCVB that his group is libertarian and opposes bigotry and the Ku Klux Klan.

If you are labeling people like that as “Nazis”, you’re REALLY expanding the definition.
