You actually don't believe that Adolph Hitler was mentally ill??   Wow, I find that to be amazing.   That man had one of the sickest minds in human history, as documented by many mental health professionals.

OK, if you want to believe that there are Nazis hiding under every rock in Springfield, and there are racists hiding in every shadow, more power to you.    But your solution here of extrication is in itself highly fascist in nature, and is totally un-American.     The Supreme Court has repeatedly ruled that such speech is Constitutionally protected.     And as has already been noted in this discussion, even the ACLU has fought to protect the free speech rights of Nazis in our courts.

Just because what they are saying is abhorrent and ugly, does not make it illegal.  

But if you want to waste the time of our Mayor and the City Council on this matter, please feel free to make your case for them to take action at the next city council meeting.
