Free speech is a right. Congress shall make no law, as they say. What some people don’t seem to understand is that entities who are not Congress, when they abridge the right of free speech, are not violating your first amendment right. Fluther, for example, violates no one’s right by deleting a comment.
What I wish people also realized, is that rights come hand-in-hand with responsibilities. If people took their responsibilities as seriously as their rights, we could avoid many problems. For instance, along with the right to free speech, comes the responsibility to not be an asshole. If people didn’t use fighting words, hate speech, or shout “Fire” in crowded theatres, we wouldn’t need to take the right away from people who don’t uphold their responsibilities.
Another thing to consider is that the Freedom of Speech doesn’t protect you from the consequences of what you are free to say. Benjamin Franklin had this to say about what should accompany the right to Free Speech:
My proposal then is, to leave the liberty of the press untouched, to be exercised in its full extent, force, and vigor; but to permit the liberty of the cudgel to go with it pari passu. Thus, my fellow-citizens, if an impudent writer attacks your reputation, dearer to you perhaps than your life, and puts his name to the charge, you may go to him as openly and break his head. If he conceals himself behind the printer, and you can nevertheless discover who he is, you may in like manner way-lay him in the night, attack him behind, and give him a good drubbing. Thus far goes my project as to private resentment and retribution. But if the public should ever happen to be affronted, as it ought to be, with the conduct of such writers, I would not advise proceeding immediately to these extremities; but that we should in moderation content ourselves with tarring and feathering, and tossing them in a blanket.
If, however, it should be thought that this proposal of mine may disturb the public peace, I would then humbly recommend to our legislators to take up the consideration of both liberties, that of the press, and that of the cudgel, and by an explicit law mark their extent and limits; and, at the same time that they secure the person of a citizen from assaults, they would likewise provide for the security of his reputation.
In other words, you can say all you want, and we should have the same right to hold you accountable for what you say. Or, if we can’t hold you accountable, perhaps there are things that ought not be allowable to say.
