That stupid and overused quote comes from an opinion by justice Holmes. "Holmes, writing for a unanimous Court, ruled that it was a violation of the Espionage Act of 1917 (amended with the Sedition Act of 1918), to distribute flyers opposing the draft during World War I." - Wikipedia.

Read the case before you quote it. American Supreme Court has done a lot of injustices in its time. And this is one of the more egregious once.
