Can cooler heads prevail in Boston?

Hot Air: "Boston Approves Permit For ‘Free Speech’ Rally."  Here's what the organizers said on their Facebook page:

While we maintain that every individual is entitled to their freedom of speech and defend that basic human right, we will not be offering our platform to racism or bigotry. We denounce the politics of supremacy and violence. We denounce the actions, activities, and tactics of the so-called Antifa movement. We denounce the normalization of political violence…

We are 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.

Boston mayor Marty Walsh had been trying to block the rally but now he's appealing for calm and reason.  Maybe we can talk to each other instead of yelling past each other.
