I don't care for what they have to say. And I'm not sure the mayor is completely correct, because "disturbing the peace" covers all kinds of stuff, including having your stereo too loud in your own home, your dog barking all night long in your own backyard. These guys were walking down the street, yelling racial insults. If that's not god damn disturbing the peace, I'm not sure what is.
"Disturbing the peace" aside, I absolutely agree with the mayor. Freedom of speech means the King George won't chuck you in a prison using a lettre de cachet, and forget about you. It doesn't mean your employer won't fire you for "conduct unbecomming an employee of Microsoft". It means you won't go to prison, and that's as far as it extends. Regardless of the reprehensibility of their message, that's part of speech freedom, unless they were advocating violence (we're going to kill all you <plural version of a black racial slur>).
So. I don't agree with what they were doing. I'm not sure why the mayor didn't have them arrested for "disturbing the peace". However, the response to the Nazi's "protest" shows the underlying social problems in Toledo, specifically the racial aggression toward "whites" in the area.
