Christopher Hitchens said here and here:
"[If] one person gets up and says:
“You know, about this Holocaust, I’m not sure it even happened. In fact, I’m pretty certain it didn’t. Indeed, I begin to wonder if the only thing is that the Jews brought a little bit of violence on themselves.”
That person doesn't just have a right to speak, that person’s right to speak must be given extra protection. Because what he has to say must have taken him some effort to come up with, might contain a grain of historical truth, might in any case get people to think about why do they know what they already think they know. How do I know that I know this, except that I’ve always been taught this and never heard anything else?
