To answer, Katt. "Freedom of Speech" is essentially "Freedom of Dissent."
The ability to influence one's society and government and through written or spoken word is absolutely critical to the maintanence of all freedoms.
The American Founding Fathers did their homework when establishing our Bill of Rights. Each Ammendment is a brick in the wall that protects our nation from tyranny, which is the natural evolutionary path of all governments. The freedom of speech may be metaphorically compared to the mortar between the bricks. Unrestricted communication is essential for citizens to be aware of what is occurring not just in their communities but the nation and world, as well allowing for organization and coordination of those with dissenting views.
Many would claim that there have too many inroads already into the Bill of Rights and I would be inclined to agree.
Note that every totalitarian regime in history has greatly restricted or outright controlled the means of communication within their territory.
Therefore, this freedom is not a question of indoctrination, essentially something having value only because we are told to value it, but for real world, practical reasons. Revolt is built into the American Bill of Rights. Each Right strengthens the ability of the populace to organize and resist would-be tyrants.

Freedom of Speech and Press: Exceptions to the 1ST Amendment
http://www.fas.org/sgp/crs/misc/95-815.pdf This document explains quite well, the very few limitations we allowed on freedom of speech and even these are under constant court challenge by different groups in our society.

<!-Quote-!>Quote:The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it. If the opinion is right, they are deprived of the opportunity of exchanging error for truth: if wrong, they lose, what is almost as great a benefit, the clearer perception and livelier impression of truth, produced by its collision with error.
-John Stuart Mill, On Liberty, 1859
If all mankind minus one were of one opinion, mankind would be no more justified in silencing that one person than he, if he had the power, would be justified in silencing mankind.
-John Stuart Mill, On Liberty, 1859
The populist authoritarianism that is the downside of political correctness means that anyone, sometimes it seems like everyone, can proclaim their grief and have it acknowledged. The victim culture, every sufferer grasping for their own Holocaust, ensures that anyone who feels offended can call for moderation, for dilution, and in the end, as is all too often the case, for censorship. And censorship, that by-product of fear - stemming as it does not from some positive agenda, but from the desire to escape our own terrors and superstitions by imposing them on others - must surely be resisted.

And finally:
I disapprove of what you say, but I will defend to the death your right to say it.
