Nearly everyone agrees with the right to free perch, but there are many where free speech could be debated. What instances can you think of where people might disagree with totally free and unrestricted speech?

An example of free speech that might be considerd a misuse of it would be Hitler writing Mein Kampf

Explanation:

Because it layed the foundatitaion for the nazi party.

I don't particularly see reasons why free speech can be bad, but in any case, when we are free to speak, sometimes things are said that should not be said. Maybe people in the media and politicians don't see so much good in that respect because it can harm them.
