Ah, freedom. Of speech - of the right for stupid people to think and say horrid things.
Of course, there were dozens of Muslim victims of the 911 attacks, but let us forget that and instead worry about:
SHARIA! We don't know what the hell it means, but if the MOOSLIMS are a'for it, we're 'agin it! Fun fact! A few southern states have passed laws banning Sharia. Whatever that means.
Imagine not living in America, maybe say instead, for example, you are a Muslim living in Turkey. And you see these protests on your TV. You must think, "America! What a country! Truly, the land of the free and home of the brave."
