"Lynching" seems to be exaggeration here, since nobody appears to be actually dying. I mention this not because I'm upset about that word, but because I disagree with the basic claim that anyone's lives or livelihoods are being destroyed. PewDiePie's account is unsuspended and he's actively posting to YouTube. He doesn't have a Disney sponsorship any more, but I don't believe he particularly has a right to a Disney sponsorship. He's welcome to make a living however he wants, just like anyone else. And just like anyone else, his past work will impact his future prospects; if I play a bad joke on my coworkers, my future employment prospects as a sysadmin will likely be limited, too. That is part and parcel of making sure that good work improves your future prospects, which seems like a desirable goal for a society.

I support PewDiePie's right to say whatever he wants. I posted a link to his own video in another comment. I am thrilled to bring it to light. I don't believe that defending his right to say it involves defending his right to receive corporate funding or popular appreciation for what he says; "I disagree but will defend your right" seems to imply quite the opposite to me.

I agree that if you find yourself destitute (or actually lynched) as a result of public outcry, your right to speech is impacted, but I don't believe there's ever been such a case. Can you point me to one?
