Do you not see how this example proves the point that not all speech is desirable or deserving of protection, and that there are limits?
You don't care for the speech of the bullhorn people ruining your concert. You think they should be stifled.
I don't care for the speech of Nazis and racists ruining my country. I think they should be stifled too.
Please don't put words in my mouth.
Of course not all speech is desirable - doh! And yes of course, as I've said several times on this very thread, there ARE limits to free speech. But not as many as people think. As for "not deserving of protection" - now that's the nut of the question. Who's smart enough to tell you what you aren't allowed to hear? I know of no one I'd give that power to.
