If we have to have "free speech zones"
But what is the meaning of "free speech zone" in an age when instant mass communication is ubiquitous? If your speech requires you to be in the face of someone else, then is it really speech you're interested in?
I want to hear lots of opinions, lots of perspectives. But it can no longer be argued that not being allowed to speak in a certain venue equals being "silenced".
The only thing that's forced on them is the knowledge of the fact that someone nearby is listening to those things.
Again, if your main concern is that your speech be "nearby", then I submit that you may be interested in something besides speech.
