Yes because free speech is a political issue
Not quite. It is a concept which has been politicized. The ideal behind free speech, as a concept, was to guarantee protection for important or unpopular speech, like speaking out against corruption. But, there is no law, or set of laws which can guarantee righteousness in all circumstances for all people. This is one of the most significant lessons from the OT. Genuinely free speech is only possible when it is regulated by wisdom.
Its only role is as a protector of individual rights including the right to free speech.
No one has the right to harm others though and it's proper for the government to step in in such a case.
This is the problem with referring to the concept of free speech as free speech. Calling it "free" gives the impression that there should be no restriction whatsoever, and yet there is no human on the earth who genuinely believes that. If someone is lying about you in a way that hurts you, your family, your ideology, or your business, you will not say that he has a right to tell such lies. The
intent behind the phrase was never meant to justify all speech of any kind for any reason. Rather, it's meant to communicate that people should have the freedom to speak up without fear of punishment if they see a problem.
Perhaps it is a maturity issue. Americans, in particular, have become so high on their own sense of righteous freedom that they've twisted it to suggest that any person opinion becomes fact by virtue that you have the freedom to express it.
In an essay by C.S. Lewis on the rather barbaric practice of vivisection (performing surgery on animals without anesthetic), he notes that many supporters of the practice justify it on the basis that we humans are superior to animals and therefore have the right to do with them as we please.
Lewis concedes that we are superior to animals, but only in so much as we behave in a superior way. Obviously, disregarding the pain we cause to others just because we can is not superior behavior. It's a bit like the king who feels the need to say, "I am the king"; when he does that, he is no longer a king.
Freedom, as a concept, only has merit when it is interpreted through the context of integrity, character, and wisdom.
