Sorry Eddie, but if that's not what freedom of speech means, then please elaborate to me what it truely means.
Just want to say, Eddie's not referring to 'freedom of thought'. That's taken as a given. There's no-one stopping you from
thinking whatever you wish. Eddie's refferring to the public exposition of said views. What he's saying is that with any views, comes responsibility for those views. If you state publically that all Jews should die and that Hitler was a genius for thinking so and some people hear that and kill some Jewish people, you wouldn't be able to fob-off any anger against you by saying "Hey, it's a free country." Incitement towards violence, as an example, means the incitee is at least partially responsible for doing so. We'd all like to believe we are all totally free thinkers, etc. but all of us have our biases/weaknesses to the power of suggestion. It all comes down to the (subjective, given) knowledge of consequences of actions/words.
If you pull a trigger of a gun at someone's head and they die from the bullet wound, a less than successful defence would comprise saying something like "Well, all I did was pull the trigger. The bullet left the gun and struck the person but I didn't make it happen. It was my fault the bullet hit the person. " Of course, we would all say that the person holding the gun should have foreseen that the person the gun was aimed at would have died. Similar with freedom of speech; if you are able to reasonably foresee consequences of your views, with that comes responsibility for those views. Hence freedom of speech isn't totally free in this society.
Second, with freedom of speech comes the onus of justification. You could hold the view that the sky isn't blue but is silver with green polka dots and although I couldn't see what you can see, I have a weight of scientific evidence which suggests it's not the case (Rayleigh Scattering and all that). Now, there's nothing preventing you from holding that view nor should there be but if you were to make it public, the burden of proof is therefore upon your head otherwise your opinion is, essentially, meaningless. Not all opinions are equal, after all. For example, if I got into a debate with Stephen Jay Gould (when he was alive....) over his theory of Punctuated Equilibrium, considering he invented it, he'd hand me my own on a platter. Ditto for most people. Why? He can justify his opinion with plenty of evidence. Anyone opposing him would have to have a similar level of evidence to be able to converse with him and those who hold an opinion otherwise, without evidence, are wasting their time and the time of those who are listening.
So, with freedom of speech (of anything, really) comes responsibility; responsibility for consequences and responsibility for justification. That's why freedom of speech isn't free, per se. Or it is but with pretty significant caveats.
