Freedom of speech

I like when the notion of freedom of speech is invoked against haters of Islam.  I am aware of the First Amendment, but can you imagine the government and public reactions if a public festival of anti-Semitism was planned anywhere in the US?  I mean, freedom of speech did not prevent the US from banning Arabic TV stations and from banning the publication of the memoirs of Abu Dawud.  It seems that freedoms of speech are abundantly available for those who wish to spread hate against Islam.
