There are many kinds of speech that are not protected by the First Amendment to the U.S. Constitution. Among them are libel, slander, treasonous speech, incitement to violence, and lies deliberately intended to defraud the listener. That is not, I think, an exhaustive list of all the exceptions, but it includes the most immediate ones that come to my mind. If you are sued on any of these grounds in court and the prosecution can prove the case, the First Amendment will not help you--nor should it.
Those who rightly object to a billionaire buying a huge social media platform with millions of users so that--as the billionaire himself has promised--it can be filled with libel, fraud, and incitement to violence, are not objecting to free speech. Nor are they objectiong to "political incorrectness." They are objecting to lies, fraud, and violence. |
