If you find someone's speech not useful you're free to ignore it, condemn it, or whatever you want.
I think I did that.
The courts luckily say you're wrong. The medium of communication is irrelevant regarding speech.
I don't think so. There is no 'FCC' or 'CRTC' mediating my comments on a streetcorner.
I think your ideas are more dangerous than anything Sam Harris has ever said, yet you're free to say them.
And yet, in your note in the top you said I'm 'free' to make comment. And now you say I'm dangerous. Hmmm.
