"'Congress shall make no law […] abridging the freedom of speech, or of the press.' What does this mean today? Generally speaking, it means that the government may not jail, fine, or impose civil liability on people or organizations based on what they say or write, except in exceptional circumstances.Although the First Amendment says 'Congress,' the Supreme Court has held that speakers are protected against all government agencies and officials: federal, state, and local, and legislative, executive, or judicial. The First Amendment does not protect speakers, however, against private individuals or organizations, such as private employers, private colleges, or private landowners. The First Amendment restrains only the government."
I may not agree with what you say, but I will fight to the death for your right to say it.
