Somehow it's the fault of a Saudi prince's exploratory investments that people in the USA want to use their constitutionally-protected right to free speech on the Internet? How absolute dare they!
There is no such thing as hate speech. There is free speech, and there is censorship. Kara Swisher seems to be mad that there is not yet enough censorship for her tastes, which I think would extend to domain registrar or even ARIN deplatforming of any site or network that dares host the comments of someone who says something she is uncomfortable with.
I find it reprehensible that anyone can even consider curtailing speech as a kneejerk reaction to violence. It's crystal clear to me that further censorship is actually going to add fuel to the fire, as those with evil opinions will have no outlet, no chance of counterargument or of being convinced toward nonviolent action, no support from other people in their emotional struggle. As though censorship will be successful this time at enabling the security of the establishment, even though it didn't work in China or Russia.
We'll painfully rediscover the lessons of the past, probably with more death and mayhem. Just as much of it will be on the hands of the censors as is on the hands of those who facilitate speech; it's up to you to decide if that's a nonzero amount.
