Kerry: 'In America you have a right to be stupid — if you want to be'

"The reason is, that's freedom, freedom of speech. In America you have a right to be stupid — if you want to be.”

Kerry was referring to a Supreme Court decision that allowed Nazi demonstrations in public. Such marches are outlawed in Germany, where even the Nazi salute and symbols remain illegal almost 70 years after the end of World War II.

His broader point comes just months after an anti-Islam video made in the United States sparked outrage and demonstrations across the Muslim world. The movie sparked efforts at the United Nations to criminalize blasphemy.

Many Muslims find it inconceivable that President Obama — the most powerful man in the world — wouldn't be able to ban such a video. In America, by contrast, the U.S. embassy's effort to distance itself from the movie outraged some conservatives who said the administration should stand up for free speech, however offensive, when it's under attack.
