When you have freedom of speech and freedom of religion, those freedoms come at a cost. One of those costs is the ability of others to say what they want, and to practice any religion that they want. Sometimes that speech and that religion (or lack thereof) can be offensive to others.
It's unfortunate that one of the more than 300 million people who live in our country legally is so rude, hateful, and stupid as to record what he did that you took offense too. It's even more unfortunate that modern technology enabled his hatred to spread around the world. But it's most unfortunate that you respond with your own vicious brand of violence and hatred.
By the way, did you notice that we've arrested him and are currently holding him in prison? And did you get that he was already a criminal in American terms --- who violated the terms of his probation in making that stupid movie? Rest assured that if there's a way to prosecute him and stop his criminal behavior - without curtailing the freedom of more than 300 million other Americans - we will do so. But I digress.
Let's talk about those Americans that you condemn and wish death for? They include over 7 million Muslims, who worship in more than 1,200 Islamic mosques ... 25% of which have been built in the last 8 years. Did you know that Islam is the fastest growing religion in America? Did you know that America has had peaceful, mutually beneficial relations with many Islamic countries for decades? Have you taken the time to get even a clue about how America really views Islam?
You see, we welcome Muslims to America and guarantee their right to free speech and freedom to be as Muslim as they want to be. And we've welcomed them here for more than 150 years. You just attacked THEIR embassy and killed THEIR ambassador. And now you protest against them and call for their death.
