Free speech keeps everything in the open where ideas can be shared, debated and discussed. Restricting free speech drives ideas underground, where they can fester and can become explosive actions. The Founding Fathers made the First Amendment the **first one** because it was critical when it came to safeguarding the Republic. You want transparency. You don't want secret cabals forming, each with their own languages. The only people who want censorship are people who are threatened by ideas and have no ideas of their own.
